[TASK] Deprecate extbase request getRequestUri()

The next step towards a PSR-7 compatible request
object in extbase is to get rid of getRequestUri()
and setRequestUri().

The strategy is similar to getBaseUri() from issue
#94223: The Internal method setRequestUri() is dropped
and the unused getRequestUri() is deprecated.

Resolves: #94228
