Fix layering_check with path stripping and textual_hdrs

Looks like the original issue is fixed here

Remove allowlist_include_directories from data

When very recent versions of bazel, improvements in the merkle tree recommend that instead of passing a huge list of files to the toolchain, you instead pass the root directory...

Silence warning with parse_headers

``` clang -xc++-header -fsyntax-only -c foo.h clang: warning: argument unused during compilation: '-c' [-Wunused-command-line-argument] ``` This just no longer passes the `-c` to the header parsing action

Bazel has quite a few "marker" type features where their presence in the toolchain is used as a signal that it supports some configuration. Here are a few examples: https://github.com/bazelbuild/apple_support/blob/af8d93a33586c80bf2d245922ce31fcd109fe645/crosstool/cc_toolchain_config.bzl#L2666-L2678...
