  Log Message:
  -----------
  Apply format only if --format is specified (#79466)

clang-apply-replacements used to apply format even without --format is
specified. This because, methods like createReplacementsForHeaders only
takes the Spec.Style and would re-order the headers even when it was not
requested. The fix is to set up Spec.Style only if --format is provided.

Also added note to ReleaseNotes.rst
