Currently CacheQueryOptions(ignoreSearch, ignoreMethod, ignoreVary) are not
supported on Cache.match/matchAll/delete/keys and CacheStorage.match, but
these APIs can accept the options and just drop them internally.

This CL makes these APIs show a warning message when unsupported options
are specified.
