  Log Message:
  -----------
  [LLD] [ELF] Make -z gcs=always implicitly warn on missing GCS, like force-bti (#186203)

This matches GNU ld, where gcs=always makes it implicitly warn about
missing GCS flags, by matching the existing code pattern used for BTI
and IBT.

Also test that warnings can be printed for both missing BTI and GCS for
the same object file.

This fixes #186173.
