Modernize and clean up petscsys.h

- Deprecate PETSC_NULL.
- Switch from preprocessor defines to anonymous enums for constant expressions.
- Surround macro arguments in ().
- Remove redundant casts.

Improves safety in AVX512 kernels

- Use masked loads when AVX512VL is available
- Disable manual remainder optimization for platforms without AVX512VL support such as KNL. This prevents reading unallocated memory but may lead to downgraded performance of MatMult() for MatAIJ on KNL.

Use PetscHMapISet() in place of PetscHMapISetWithMode(INSERT_VALUES) as the intent is clearer

- Replace PetscTable with PetscHMapI.
- Rename:
- PetscTableCreate() -> PetscHMapICreateWithSize()
- PetscTableFind() -> PetscHMapIGetWithDefault()
- PetscTableAdd() -> PetscHMapISetWithMode()
