[TASK] Avoid unused DataProviderContext

TYPO3\CMS\Backend\View\BackendLayout\DataProviderContext
is only relevant in DataProviderCollection when calling
getBackendLayoutCollections().
TYPO3\CMS\Core\Page\PageLayoutResolver only calls
getBackendLayout(), so the setup of DataProviderContext
is not needed.
The patch resolves this and thus reduces the dependencies
from ext:core to ext:backend.
