[NewPM] Port HWASan and Kernel HWASan

Port hardware assisted address sanitizer to new PM following the same guidelines as msan and tsan.

Changes:
- Separate HWAddressSanitizer into a pass class and a sanitizer class.
- Create new PM wrapper pass for the sanitizer class.
- Use the getOrINsert pattern for some module level initialization declarations.
- Also enable kernel-kwasan in new PM
- Update llvm tests and add clang test.
