[Basic] Remove unused includes (NFC) (#142295)

kazutakahirata · web-flow · commit cd9fe8a34cfb · 2025-05-31T19:00:31.000-07:00
These are identified by misc-include-cleaner.  I've filtered out those
that break builds.  Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.
