Work around MacOS compilation issue with embed stlib (#2255)

- The enable-stdlib-generator project is created with
  'kind = StaticLib' to allow the build to work, even though
  the project doesn't actually create a library.

- Unlike some other platforms, MacOs "ar" emits an error if no
  object files are listed to be added to an archive. This causes
  enable-stdlib-generator to fail on MacOS.

- Changing the project's kind to "SharedLib" works around the issue.
  Other values for kind do not seem to work around the issue.

- Add an optional flag to generatorProject to indicate that
  kind = "SharedLibrary" should be used, rather than "StaticLibrary"

- Add MacOS fix for SharedLibraryUtils::getSharedLibraryFileName().

- Enable embed stdlib in github_macos_build.sh
