Daniil Kovalev 3b162f73d8 [PAC][clang] Add signed GOT cc1 flag (#96160) ...

Add `-fptrauth-elf-got` clang cc1 flag and set `ptrauth_elf_got`
preprocessor feature and `PointerAuthELFGOT` LangOption correspondingly.
No additional checks like ensuring OS binary format is ELF are
performed: it should be done on clang driver level when a pauth-enabled
environment implying signed GOT enabled is requested.

If the cc1 flag is passed, "ptrauth-elf-got" IR module flag is set.
