[feat] [protobuf] Improve protobuf generator with switch useSimplifiedEnumNames

[andrewwilsonnew]

#21054

@wing328 we generate wire classes with our protos so we'd like the enum names to be FOO rather than TEST_STRING_ENUM_FOO. I've added a switch useSimplifiedEnumNames (default old value). Any chance we could get this into the patch?

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package || exit
  ./bin/generate-samples.sh ./bin/configs/*.yaml || exit
  ./bin/utils/export_docs_generators.sh || exit
  

  (For Windows users, please run the script in Git BASH)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• File the PR against the correct branch: master (upcoming 7.x.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Modelled this test on this one

[andrewwilsonnew]

If you want to look at the output flip this flag and run the generator, but this is covered by unit tests

We could also test the output by adding the flag in bin/configs/protobuf-schema-config.yaml .
