[ruby] Build/test ruby 3.4 and build native gems with Ruby 3.4 support (

grpc#38338)

Updates ruby-compiler-dock to `1.7.1` to [bring Ruby 3.4 support](https://github.com/rake-compiler/rake-compiler-dock/releases/tag/v1.7.0) and starts cross-compiling native gems for Ruby 3.4. Added a distribtest as well.

I believe from last year at grpc#35399 that this probably requires @apolcyn or another Googler to build+push+update the `grpc-testing` images, along with

- `tools/dockerfile/push_testing_images.sh`
- update the values within [the current_version files](https://github.com/grpc/grpc/tree/9b77138b71e04bb127ec1fb3ae280bca33c59ae1/third_party/rake-compiler-dock).
re-run generate_dockerimage_current_versions_bzl.sh and commit changes to dockerimage_current_versions.bzl.
- similar for the `ruby_debian11_x64_ruby_3_4` image added here (needs to be built and pushed)

Marking as draft until we are happy with approach. Note that fully pre-compiled install wont be possible until protobuf pushes their own 3.4 native versions via protocolbuffers/protobuf#19752 (and a release), but this does not seem to block things as protobuf compile seems to be working OK without code change right now.

Closes grpc#38338
