Remove unused vector drawable code path (#46878)

Summary:
Pull Request resolved: #46878

Removes an unused code path from `ResourceDrawableIdHelper`. Vector drawables are now loaded via Fresco decoder so we don't need to offer this utility anymore. While part of the public API, it only made it into 0.76.0 RCs and should have really been marked internal.

Changelog: [Internal]
