[FEATURE] Allow placeholders in Backend URLs

This change introduces a Backend Route Result,
similar to the Frontend Route Result object,
using symfony's native URL routing component
in TYPO3 Backend now, to allow to use placeholders
in the URL. The Backend Route Result now
contains the resolved Route object and
the arguments defined in the Route, which
are then resolved during the PSR-15 middleware
when the Router kicks in.

Note: In a later stage Router->matchRequest()
will be deprecated.
