Summary: Reduce boiler plate for Go container image C++ headers

Previously, adding a new Go version required:

1. Creating new header files for each container type (grpc_server, grpc_client, tls_server, tls_client)
2. Adding BUILD.bazel entries for each new library
3. Updating test files with new #include statements

These header files account for ~100-200 lines of boilerplate code per Go version (~50 lines for each grpc and tls client/server pair) and add overhead when upgrading our Go version.

This PR reduces this boilerplate by generating these files with a new Bazel macro go_container_libraries. This macro generates:

• Individual C++ headers for each version (e.g., go_1_24_grpc_server_container.h)
• Aggregate headers that include all versions for a given container type (e.g., go_grpc_server_containers.h, go_tls_client_containers.h)

Relevant Issues: N/A

Type of change: /kind cleanup

Test Plan: Build should succeed
