[Ruby] Stop stripping exported symbols

[peterzhu2118]

This commit stops stripping exported symbols in the compiled binary. This will ensure that functions like Init_grpc and ruby_abi_version are not removed from the generated binary.

Fixes #30976.

Thanks - this lets grpc compile under Ruby 2.7.4 [tested]

@apolcyn can we please make this a priority to merge and release? It's blocking Mac M1 users from installing latest GRPC on Ruby with this error:

linking shared-object grpc/grpc_c.bundle
Undefined symbols for architecture arm64:
  "_ruby_abi_version", referenced from:
     -exported_symbol[s_list] command line option
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [grpc_c.bundle] Error 1

make failed, exit code 2

Gem files will remain installed in /Users/drineliu/.rbenv/versions/3.1.2/lib/ruby/gems/3.1.0/gems/grpc-1.50.0 for inspection.

@johnnyshields A work around is that you may run

bundle config build.grpc --with-ldflags="-Wl,-undefined,dynamic_lookup"

before bundle install

This should allow the gem to build on Apple Silicon/XCode 14

@apolcyn any update on this?

[apolcyn]

Thanks for the PR @johnnyshields and sorry for the review delay.

Thinking about this more, I'm actually favoring a slightly different approach - I opened #31970 - PLMK if you have any thoughts about that.
