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.
