This will be used for tracking the unresolved feature sets from the original proto file. Notable use-cases for this include:
* Code generators that need to validate their own features
* Runtimes that need to be able to accurately round-trip the original protos

Adding composer config to allow the native protobuf extension to provide ext-protobuf.
This allows libraries to require at least one protobuf implementation. If the extension is not available, it can be provided by the native package. If the extension is available but the native package is required, the native will be installed.
Importantly, for libraries which require at least one of them to be installed, composer will complain if neither is available.
Closes#13141

If you are running an older version of PHP, you can install a previous release
of the protobuf PHP extension by running pecl install protobuf-3.23.3.

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.

An extension range is either of verification state "UNVERIFIED" or "DECLARATION". If "DECLARATION", all extension fields of the range must be declared, or build error otherwise. The current default is "UNVERIFIED", but we will flip the default later.
Deprecate `is_repeated` in favor of `repeated`.

This can be useful when an extension field/declaration is deleted in schema to avoid data corruption.
It also adds a check for duplicate numbers in the declarations.
