Improve method mappings, particularly for specialized methods

[SpaceWalkerRS]

1. Some methods inherited from libraries or the JDK, and while the synthetic bridge methods are not obfuscated, the specialized methods are. Rather than giving these methods intermediary names, these methods should inherit the name from their bridge counterpart.

2. The same should happen for MC's own methods. This makes method inheritance clearer as all methods in the entire inheritance chain will have the same name. This will require an update the Mapping Utils' Propagator though, as it assumes intermediary names are entirely unique within a class.

100% agree, the specialized/bridge methods need better handeling.
