The new fields fixed_features and overridable_features can be simply merged to recover the old aggregate defaults. By splitting them though, plugins and runtimes get some extra information about lifetimes for enforcement.

The only public target here is the edition defaults helper macro, which can be used by external runtimes and plugins. None of this code is C++-specific though, and should be organized higher up. Appropriate aliases are also placed at the top level for public targets

Features need to be validated within the pool being built, since the generated pool only contains extensions linked into the binary (e.g. protoc or a runtime building dynamic protos). The generated pool may be missing extensions used in this proto or it may have version skew. Moving to the build pool requires reflective parsing, which in general can't be done from inside the pool's database lock. This required some refactoring to add a post-build validation phase outside of the lock.
For now, the feature support spec is optional and the checks only are only applied when it's present. Follow-up changes will add these specs to our existing features and then require them for all FeatureSet extensions.

This updates all our text parsers and serializers to better handle tag-delimited fields under editions. Under proto2, groups were the only tag-delimited fields possible, and the group name (i.e. the message type) was guaranteed to be unique. Text-format and various generators used this instead of the synthetic field name (lower-cased group name) to represent these fields.
Under editions, we've removed group syntax and allowed any message field to be tag-delimited. This breaks those cases when adding new tag-delimited fields where the message type might not be unique or correspond to the field name. Code generators have already been fixed to treat "group-like" fields using the old behavior, and treat new fields like any other sub-message.
This change addresses the text-format issue. Text parsers will accept *either* the type or field name for "group-like" fields, and only the field name for every other message field. Text serializers will continue to emit the message name for "group-like" fields, but also use the field name for everything else.
This creates some awkward capitalization behavior for fields that happen to *look* like proto2 groups, but it won't lead to any conflicts or invalid encodings. A feature will likely be added to edition 2024 to allow for migration off this legacy behavior.

They are not needed after the rules are move into protobuf repo.
Except for the reference to toolchain type, which is currently in rules_proto and can be moved after the implementation is moved into protobuf repo.

In the _RegularMessageToJsonObject method, there is no str type conversion for non-bytes type values in the repeated content. This causes an exception in the MessageToJson method, as the jsons data does not allow for the occurrence of byte array type property values.
BUG EG (contains proto and python code)：
------------common.proto------------
message SafetyInfo{//
repeated LoginDevice deviceList = 1;
}
message LoginDevice {
optional string uuid = 1 [default = ""];
optional string deviceName = 2 [default = ""];
optional string deviceType = 3 [default = ""];
required uint32 lastTime = 4;
}
------------test code(python)------------
from google.protobuf.json_format import MessageToJson
import common_pb2 # generate by common.proto
pb = common_pb2.SafetyInfo()
pb_hex = "0a4e0a2039323833663530356533363332396338356638623866343832613561323061651211636d4a38426c307a4d20446576696365731a0f6950686f6e6520694f532031332e3720dc85a9b00628010a410a206233356161326632366236343966313536393466663761336263303434323163120950432dcdacd0cbb4ef1a0a57696e646f777320313020d5d2c6e705280010001800200028003001" pb.ParseFromString(bytes.fromhex(pb_hex))

This is needed after python/dist:dist's limited_api_wheels was updated from 3.7->3.8 and was causing us to mislabel the python_tag for our 3.8 limited api wheels as the system python version of 3.7.
Also:
* Add LINT to prevent next time
* Clean up some documentation

This is needed to make protobuf/bazel package minimal for other proto rules.
Keep 4 public bzl files in upb/bazel. They end up under protobuf/bazel, and they are legitimately used by other repositories.
Move upb_proto_library_internal/* under bazel/private. Those are utilities used in the rules. Moving them one level deeper makes protobuf/bazel package clean for other rules.
Move build_defs.bzl and amalgamation under /upb/bazel. Those are utilities used in the build.
Move lua.BUILD and python* uner /python/dist. Those are used in the WORKSPACE dependency setup.

The “in” operator will be consistent with HasField but a little different with Proto Plus.
The detail behavior of “in” operator in Nextgen for Struct (to be consist with old Struct behavior):
-Raise TypeError if not pass a string
-Check if the key is in the struct.fields
The detail behavior of “in” operator in Nextgen(for other message):
-Raise ValueError if not pass a string
-Raise ValueError if the string is not a field
-For Oneof: Check any field under the oneof is set
-For has-presence field: check if set
-For non-has-presence field (include repeated fields): raise ValueError

Features are designed as temporary migration tools, and any unbounded type leaves the system open to unexpected use. Features should have a fixed set of values, with well defined behaviors.

This prevents these from using abc.ABCMeta metaclass to avoid deprecation warning:
```
DeprecationWarning: Type google._upb._message.MessageMapContainer uses PyType_Spec with a metaclass that has custom tp_new. This is deprecated and will no longer be allowed in Python 3.14.
```

The replacement always_print_without_presence_fields should be used instead, which is very similar but has consistent handling of optional fields by not affecting them.

This copy of `setup.py` is obsolete, as it builds the old C++ backend for Protobuf, which has been deprecated and
unused since 4.21.0 when
[the backend was switch to upb](https://protobuf.dev/news/2022-05-06/#python-updates).
The `setup.py` that we actually distribute in our source packages is located in [`python/dist/setup.py`](https://github.com/protocolbuffers/protobuf/blob/main/python/dist/setup.py). It is not possible to build this `setup.py` directly from the GitHub repo or GitHub release tarball, because it depends on the file layout of our Python source package ([as distributed on PyPI](https://pypi.org/project/protobuf/#files)). The Python source package uses a layout that pulls together all of the things Python needs:
|Python Source Package Path|GitHub Repo Path|Description|
|-----|-----|-----|
|`setup.py`|`python/dist/setup.py`|
|`google/protobuf/*`|`python/google/protobuf/*`|pure Python sources|
|`python/*`|`python/*`|C extension sources|
|`utf8_range/*`|`third_party/utf8_range`|C UTF-8 Validation Library|
|`upb/*`|`upb/upb/*`|C Protobuf Library|
Users who want to build their own Python packages should build from our source package on PyPI, not from our GitHub repo or our GitHub release tarball.
It is also possible to build our source package from GitHub using the following command (this requires Bazel):
```
$ bazel build //python/dist:source_wheel
```

This disables all checks of json_name for upb and protoc under both proto2 and proto3. This option is deprecated that will be removed in future versions, and is only meant as a temporary solution. This also fixes a latent bug in the calculation of camelcase name in Python/upb.
Fixes#12525

This flag has consistent behavior between proto2 and proto3 optionals (by not including either one), unlike including_default_value_fields which does include proto2 optional but excludes proto3 optionals.
including_default_value_fields is now deprecated and will be removed in an upcoming release.

Also hardened the text format printer against invalid UTF-8 in string fields. The output string will always be valid UTF-8, even if string fields contain invalid UTF-8.
