bazel: Limit define scope to specific cc targets (see #3757) 

- Add `declare_[cc|objc]_library` macros to configure common `copts`
  and `local_defines` (where supported) on `[cc|objc]_library`
  targets. This limits the scope of defines to the specific target
  without inheritance by dependent targets.
- `objc_library` does not currently support `local_defines` so we
  use `copts` instead of MacOS.
- Use `**kwargs` to pass all other arguments to the actual cc
  target declaration.
