[Build] Some improvement to bzlmod (#38686)

A few changes to improve bzlmod

- Added development dependencies (see [bazel_dep](https://bazel.build/rules/lib/globals/module#bazel_dep)) which are used only when developing gRPC.
- Added more tests to `bazel_build_with_bzlmod_linux.sh`
  - Added all root target except `grpcpp_csm_observability` which is not possible at this point.
  - Added building `examples/cpp` test.
  - Added a few basic test run test.

Closes #38686
