[libc][linux] add support to parse PT_GNU_PROPERTY (#174772 )

In order to add Control-flow Enforcement Technology (CET) Shadow Stack
(SHSTK) support, we need to parse the `PT_GNU_PROPERTY` program header
and the corresponding section to evaluate if the binary being started
was compiled with the necessary support.

PS: This is my first PR to llvm-libc, I might have made obvious styling
mistakes so I'd appreciate any feedback or suggestions to improve it.

I have a prototype branch using this change to enable SHSTK support:
