This caused an issue on some platforms where `protobuf/java/core/src/main/java/com/google/protobuf/java_features.proto` was getting turned into the invalid path `java/core/src/main/java/com/google/java_features.proto`.
Fixes#14862

Unlike Arena::CreateMessage, Arena::Create creates only the top level object
from arena even if it is arena constructalble; e.g. messages, RepeatedPtrField,
etc. This renders arenas less effective.
Instead of asking users to be aware of such nuances to use the right API for
the right type, this CL makes Arena::Create recognizes and fully supports arena
constructable types.
While extremly rare, some users try to emulate Arena::CreateMessage with
Arena::Create by passing arena parameter twice. For example,
```
auto foo = Arena::Create<Foo>(&arena, &arena); // bad
```
This pattern is not supported and will break after this change. The following
is recommended instead.
```
auto foo = Arena::CreateMessage<Foo>(&arena); // recommended
auto foo = Arena::Create<Foo>(&arena); // after this change
```

We transformed the proto2/proto3 protos to editions, and then run the same set of tests over both. This will verify that migrating to editions preserves the same proto2/proto3 behavior. These will not be enabled by default, and require a flag `--maximum_edition=2023`.
Future changes will:
- add more targeted editions-specific tests
- clean up our conformance test framework to allow for more targeted tests
- add wildcards to failure lists in limited cases to reduce noise
- add feature resolution conformance tests

These utilities provide a way to embed a FeatureSetDefaults message into generators or runtimes that need to implement feature resolution. They use protoc to handle the tricky reflection-based algorithm over feature protos, leaving only simple merges to be implemented in other languages. See docs/design/editions/editions-life-of-a-featureset.md for more information.

This is likely the cause of our macos cmake flakes. Both the lite and full tests trigger codegen of the lite protos, but there's no dependency between them. This creates a race condition, where it's possible for the files to be invalid by the time one of their builds is triggered. This is consistent with the error message we see:
liblibtest_common_lite.a(unittest_lite.pb.cc.o) has no symbols

The current logic of finding a suitable include path relies on CMake to always return a meaningful relative path. On Windows, however, if the two paths reside on different drives (e.g. `c:/Users/Me` and `d:/project/`) the absolute path gets returned unaltered. This yields the invalid final path `c:/Users/Me/d:/project/`.
This case is now detected and the corresponding include path is deemed unsuitable.

This will reduce the number of times our test protos are built, and may fix the flakes we're seeing in aarch64. At the very least, it should reduce them by a factor of 3 and marginally speed up our builds.

This works for both built-in generators and plugins written in C++. Any feature extensions specified by this virtual method will end up fully resolved in the descriptors.

This will allow us to run the CMake test from within the protobuf repo's Bazel
workspace. The directory structure is a little bit different depending on which
workspace the test is invoked in.

I found that this test fails when I try to run it from our protobuf repo CI
setup, probably because rsync is not available in the Docker image there. Let's
just use `cp` instead so that the test works even if rsync is unavailable.

pkg_files() has some odd quirks, like breaking if a filename exists in multiple directories. filegroup() does everything we need, without these quirks.

This represents the future direction of protobuf, replacing proto2/proto3 syntax with editions. These will enable more incremental evolution of protobuf APIs through features, which are individual behaviors (such as whether field presence is explicit or implicit). For more details see https://protobuf.dev/editions/overview/.
This PR contains a working implementation of editions for the protoc frontend and C++ code generation, along with various infrastructure improvements to support it. It gives early access for anyone who wants to a preview of editions, but has no effect on proto2/proto3 syntax. It is flag-guarded behind the `--experimental_editions` flag, and is an experimental feature with no guarantees.

After this change, `mini_table` only has MiniTable definitions themselves. Everything having to do with the MiniDescriptor wire format is in `mini_descriptor`.
Also rearranged some of the files in mini_table to have better structure for `internal/`.
This CL contains no functional change.

This simplifies the CMake code to ask for the minimum required version and also allow newer policies.
It also uses `target_include_directories()` to set the header search path in each library (and their downstream dependencies). Using `include_directories()` is not idiomatic in CMake >= 3.0. It sets the include path for all targets and one may need to have a few targets with a different search path.

This additional if is necessary as of abseil 20230125.3 when abseil is consumed via add_subdirectory,
the abseil_dll target is named abseil_dll, while if abseil is consumed via find_package, the target is called `absl::abseil_dll` .
Once https://github.com/abseil/abseil-cpp/pull/1466 is merged and released in the minimum version of abseil required by protobuf, it is possible to always link `absl::abseil_dll` and `absl::abseil_test_dll` and remove the if.
You may wonder how linking worked at all before when `protobuf_ABSL_PROVIDER STREQUAL "package"`, as `abseil_dll` was not an imported target defined by `find_package(absl)`. The reason behind this is that if a name that is not an imported target is passed to `target_link_libraries`, it is just regarded as a C++ library name. So, in the end the `abseil_dll` library was correctly linked, simply all the transitive usage requirements defined by the `absl::abseil_dll` target were not propagated, that could lead to compilation errors if abseil was compiled with the `ABSL_PROPAGATE_CXX_STD` CMake option enabled.
