Subject: Bazel: Support layering_check and parse_headers

The layering_check feature ensures that rules that include a header
explicitly depend on a rule that exports that header. Compiler support
is required, and currently only Clang 16+ supports diagnoses
layering_check failures.

The parse_headers feature ensures headers are self-contained by
compiling them with -fsyntax-only on supported compilers.
