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.

//// Note: preprocessor features exactly match corresponding clang driver flags. However, some flags are only intended to be used in combination with other ones.
|
|
//// For example, -fptrauth-init-fini will not affect codegen without -fptrauth-calls, but the preprocessor feature would be set anyway.
