[google-cloud-cpp] add v2.28.0 version

[dbolduc]

google-cloud-cpp/2.28.0

• Add version 2.28.0 of google-cloud-cpp.
• Remove version 2.12.0, and clean up code only relevant to 2.12.0.
• Simplify handling of some legacy proto libraries from Proto libraries in external/googleapis/ are always compiled googleapis/google-cloud-cpp#8022
• Drop the MSVC patch from previous versions which was fixed upstream in cleanup: remove SelectMSVCRuntime.cmake googleapis/google-cloud-cpp#13777
• Individual compute_${foo}_protos libraries were removed in fix(compute): shorten paths for Bazel+MSVC googleapis/google-cloud-cpp#13836 so mirror that here.

Tested with the following on linux:

for v in "2.28.0" "2.19.0" "2.15.1"; do
  env CC=gcc-11 CXX=g++-11 conan create --build missing  --build-require  --version ${v} recipes/google-cloud-cpp/2.x
done

@jcar87 - Hey, I could use some help. It looks like there is not a prebuilt grpc/1.54.3 package with compiler.cppstd=17. What should I do about this?

Is it possible to build a gRPC package in this configuration and retry the build? Should I change something in google-cloud-cpp.

ERROR: Missing prebuilt package for 'grpc/1.54.3'. You can try:
    - List all available packages using 'conan list "grpc/1.54.3:*" -r=remote'
    - Explain missing binaries: replace 'conan install ...' with 'conan graph explain ...'
    - Try to build locally from sources using the '--build=grpc/1.54.3' argument

@dbolduc Why are there 3 versions in the CI pipeline and not just google-cloud-cpp/2.28.0?

We're looking into this! in this case it is because of the version of abseil being used in this recipe, you could probably expand it to cover the same range as the grpc recipe:

"abseil/20230125.3" -> "abseil/[>=20230125.3 <=20230802.1]"

@dbolduc Why are there 3 versions in the CI pipeline and not just google-cloud-cpp/2.28.0?

the recipe file is shared amongst multiple versions, so if its modified, a new recipe revision needs to be published for the earlier versions as well

@jcar87 Thanks for the insight, I wasn't aware of this.

Worth a try. Thanks for looking! 🤞
