[BUGFIX] Fix FAL meta data extraction priorities

File meta data extractors have to provide an execution priority and a
data priority. The execution priority, which was previously ignored, is
now respected and extractors are ordered accordingly in
ExtractorRegistry.

Extractors with the same data priority can now provide data, while the
data was overwritten previously.

ExtractorRegistry::getExtractorsWithDriverSupport now returns a flat
array of extractors again, not a nested one like introduced in #64942,
just like annotated.

Because this fix might change the order of the execution of extractors,
it can be considered slightly breaking, thus TYPO3 11.5 is not targeted.
