[PAC][clang][test] Implement missing tests for some PAuth features (#100206) 
Implement tests for the following PAuth-related features:

- driver, preprocessor and ELF codegen tests for type_info vtable
pointer discrimination #99726;

- driver, preprocessor, and ELF codegen (emitting function attributes) +
sema (emitting errors) tests for indirect gotos signing #97647;

- ELF codegen tests for ubsan type checks + auth #99590;

- ELF codegen tests for constant global init with polymorphic MI #99741;

- ELF codegen tests for C++ member function pointers auth #99576.
