We generate these constants to enable map operations, but this is no longer
necessary now that we can get the relevant size and alignment information for
each message through its vtable.

Protobuf uses utf8_range library for utf8 string validation.
Currently, only SSE implementation is integrated.
This patch adapts utf8_range Neon implementation to protobuf.

add the traits for their dependencies.
Move StrongPointerToType to the new traits and remove the old codegen for it.
We will extend these traits to contain more information.

Functions like `map_get` return a rust Option, which
might conflict with a `message Option` defined in the
current proto file. Use `::__std::option::Option` to
disambiguate rust Option and message Option.

If this code is in every method, it's making every method larger, putting
pressure on the instruction cache.
The string formatting is an exceptional case that shouldn't slow down the
regular case.
This should modestly speed up the code in here. And besides, it's just a little
nicer to have this formatting centralised.

This will simplify runtime code that wants to access and use the structures.
This is a refactor with no expected behavior change.

Move hpb::internal::{Serialize, HasExtensionOrUnknown, GetOrPromoteExtension, DeepCopy, DeepClone} to message_lock.h as they all use the message lock
absl status helpers are now housed in status.h

Github dropped support for the current image:
https://github.com/actions/runner-images/issues/10559
There is a new image that has visionOS, but it is listed as
"beta", so it might make sense to wait and revisit when
generally updating the macOS images/tools.

On Android, this generates better assembly code, bounds-checking through all
the used indices upfront, and branching to deoptimise if it's not true,
avoiding doing 4x bounds checks. We also don't generate 4 different
`pThrowArrayBounds` code sections.

Code size Comparison:
- `void X.writeFixed32NoTag__before(int) [292 bytes]`
- `void X.writeFixed32NoTag__after(int) [180 bytes]`
This starts by throwing a more meaningful length (4bytes or 8bytes for fixed64), which makes sure the value of position in the catch clause isn't dependent on which line threw the exception.

The rules in protobuf and built-in Bazel don't mix well. Different aspects may cause actions conflicts. The safest way is to use built-in rules whenever they are still present.
proto_library should be safe, because it's not using an aspect. py_proto_library never had a built-in implementation, so it's also safe.
This still makes it possible to use the rules on Bazel 7, but only with --incompatible_autoload_externally enabled.

The source was becoming unmanageable at ~3500 LOC. It was also cumbersome to run just the `RepeatedField` or `RepeatedPtrField` subset of tests after modifying their respective implementations in the respective sources.

For cross-compilation, we may not want to re-use the same protoc which would be used during a CMake build (these would differ in hostPlatform).
Instead, allow for invocations of `protobuf_generate` pass their preferred programs, similar to how you can do this for grpc plugins.
Optional proposal:
Use `find_program`, however, this is a pretty big behavior change, this PR allows you to "opt-out" of the legacy behavior, but users shouldn't see a difference unless they opt-in to passing their own protoc-exe command/path

This came up as a pull request here:
https://github.com/protocolbuffers/protobuf/pull/18239.
|tmpnam| is ugly and would be nice to avoid.
We don't necessarily want to substitute out GetTemporaryDirectoryName with
|std::filesystem::temp_directory_path| -- the current setup creates a
subdirectory under the tmp directory and uses TempDirDeleter to clean it up.
We want to preserve that behaviour: the current setup plays nicely with bazel
without polluting /tmp with unbounded growth.

The immediate motivation for this is that it will facilitate writing a blanket
implementation of `ProxiedInMapValue` for C++-backed messages. The default
instance gives us access to the message vtable in cases where we don't already
have a message to work with.
However, it also seems generally useful just to have an implementation of
`Default`, so I implemented it for both C++ and upb-backed message views.

This was untested before.
Some of the test names had drifted from the code's names; update those.
These tests have surfaced some problems around inconsistent exception types thrown.

These tests were (generally) looping over OutputType already. Some tests were looping over a subset; I've expanded many tests to loop over more OutputTypes.
But the first failure they encountered with any OutputType meant they'd halt
that test, without testing the other OutputTypes. That's frustrating.
We use `assume()` to discard tests in the matrix that are irrelevant.
There are many java parameterized test runners. I followed the lead of
third_party/java_src/protobuf/current/javatests/com/google/protobuf/IsValidUtf8FourByteTest.java,
which uses Paramaterized runner.
This means:
- We see which output type is failing in the test name.
- We don't have to always assertWithMessage(OutputType.name()). We can just use
assertThat. Nice.
- It's really easy to add new coders, and run all the tests against them. I've
done that here for NIO encoders with offset, increasing their test coverage.
