176bf50c - [clang][NFC] Move Bounds Safety Sema code to `SemaBoundsSafety.cpp` (#99330)

[clang][NFC] Move Bounds Safety Sema code to `SemaBoundsSafety.cpp` (#99330) This patch adds a new `SemaBoundsSafety.cpp` source file and moves the existing `CheckCountedByAttrOnField` function and related helper functions and types from `SemaDeclAttr.cpp` into the new source file. The `CheckCountedByAttrOnField` function is now a method on the Sema class and now has doxygen comments. The goal behind this refactor is to clearly separate the `-fbounds-safety` Sema code from everything else. Although `counted_by(_or_null)` and `sized_by(_or_null)` attributes have a meaning outside of `-fbounds-safety` it seems reasonable to also have the Sema logic live in `SemaBoundsSafety.cpp` since the intention is that the attributes will have the same semantics (but not necessarily the same enforcement). As `-fbounds-safety` is upstreamed additional Sema checks will be added to `SemaBoundsSafety.cpp`. rdar://131777237
