Add option to disable header inclusion check

### Description of the feature request:

In my CI environment, I see builds randomly fail with errors like this (with protobuf-29.3 imported via MODULE.bazel).

```
this rule is missing dependency declarations for the following files included by 'src/google/protobuf/any_lite.cc':
'bazel-out/k8-opt-exec-ST-d57f47055a04/bin/external/protobuf~/src/google/protobuf/_virtual_includes/protobuf_lite/google/protobuf/port.h'
```

The randomness of this error plus the need to clean the bazel cache (which doesn't always make the error go away) wastes countless hours of time. I would love to have a flag like `--incompatible-ignore-header-checks` which made these errors non-fatal

Reproduce the reported Bazel 7.4.0 failure with protobuf-29.3 imported through MODULE.bazel, focusing on src/google/protobuf/any_lite.cc and the generated port.h path. Trace the header inclusion check and define coverage for the requested flag so the diagnostic becomes non-fatal while default behavior remains unchanged.
