[PAC][ELF][AArch64] Encode several ptrauth features in PAuth core info (#102508)
For llvm_linux platform, define the following meaning for bits 9, 10,
11:
- bit 9: set if indirect gotos signing is enabled;
- bit 10: set if type info vtable pointer discrimination is enabled;
- bit 11: set if function pointer type discrimination is enabled.
