common: Miscellaneous cleanups (#7239)

* code: Remove some old msvc workarounds

* android: Upgrade to NDK 26

* Allows access to newer libc++

* common/swap: Make use of std::endian

Allows removing a bunch of defines in favor of a two liner.

* common: Remove misc.cpp

* GetLastErrorMsg has been in error.h for a while and also helps removing a depedency from a hot header like common_funcs

* common: use SetThreadDescription API for thread names

* common: Remove linear disk cache

* Has never been used?

* bit_set: Make constexpr

* ring_buffer: Use feature macro

* bit_set: Use <bit> and concepts

* gsp_gpu: Restore comment

* core: Ignore GCC warning
