llvm_tools: Restructure most patch_manager modes

This is an attempt to gradually replace some of the
behavior of patch_manager.py with a more extendable
structure.

Instead of having the same code handle every patch_manager.py
mode, instead we can have a dispatch for supported modes,
and the fallback to legacy when we can't separate the
existing behavior.

This does not change the external API of patch_manager.py
at all. All unittests still pass, and we're still
applying patches correctly as expected.

TEST=cp patch_manager.py patch_utils.py ${llvm_files}/patch_manager/ \
