Reapply "Add gcc_quoting_for_param_files feature (#314)"

[brentleyjones]

This reverts commit cf271a3.

This adds a dependency on bazel_features in order to know when it's safe to enable gcc_quoting_for_param_files by default.

I'm not sure on the apple_support_extra_dependencies abstraction. Probably better to just have the bazel_features_deps() call listed in our snippet, similar to the rules_xcodeproj instructions. Also, it's technically a breaking change to add this for WORKSPACE users, but similar to how we handled it in rules_swift, we won't be upgrading the major version for this.

[brentleyjones]

Now I just need to remember to add a note in the release notes.

I think you'll need to update this too: https://github.com/bazelbuild/apple_support/blob/master/.github/generate-notes.sh
