[BUGFIX] Abuse of storage 0 for extension resources

This patch makes sure the virtual storage 0 is not longer abused by the
StaticFilesProcessor. Therefor the StaticFilesProcessor now returns URIs
of the provided files and not longer FILE objects.

All `EXT:` references are now properly resolved through
`PathUtility::getPublicResourceWebPath()` if available (TYPO3 11.4.0 and
higher) or by providing an absolute path to
`PathUtility::getAbsoluteWebPath`.

FAL resources are resolved using `PathUtility::getAbsoluteWebPath` also
by providing an absolute path.

The new behavior is disabled by default and can be enabled by setting
"compatibilityMode" to "false".
