feat: impl Name for some well-known types

[sillykelvin]

Implement the newly added Name trait for well-known wrapper types, e.g. google.protobuf.Empty.

The CI failed due to compiler version requirement mismatch:

error: package regex-syntax v0.8.2 cannot be built because it requires rustc 1.65 or newer, while the currently active rustc version is 1.64.0

Anyone who knows how to fix the CI failure? Thanks!

Please rebase to latest master to fix CI.

I would like to see some tests. You could add something like this to tests/src/type_names.rs:

    assert_eq!("BoolValue", bool::NAME);
    assert_eq!("google.protobuf", bool::PACKAGE);
    assert_eq!("google.protobuf.BoolValue", bool::full_name());
    assert_eq!("type.googleapis.com/google.protobuf.BoolValue", bool::type_url());

This function is specific to googleapis url. I would reflect that in the function name.

Suggested change

	fn type_url_for<T: Name>() -> String {
	fn googleapis_type_url_for<T: Name>() -> String {
