Remove C++20 Patches from ReactCommon Files

[chiaramooney]

Remove patches needed because RN is on C++20 and we use a lower version. Patches were made to ShadowTree.cpp, NumericBitfield.cpp, Config.h, LayoutResults.h, UIMangerBinding.cpp, and Node.h.

Need to make a decision on whether we update this for 0.73. Doesn't seem like there's a reason for us to not match core and use this latest. Just need to make sure any customers who can't make that move have a clear path.
