Genode: constrain `osTryAllocPages` to RAM quota (#6883)

Genode software components all start with an explicit RAM resource quota
which may or may not be upgraded during runtime by the parent process.
With this patch `osTryAllocPages` will fail if allocation exceeds quotas
set by the parent and the `osAllocPages` procedure will trigger a
blocking request to the parent to increase quotas. The previous behavior
could potentially block both procedures indefinitely for a quota upgrade
rather than fail and trigger garbage collection.

This patch also adds tracking of Genode dataspace mappings into the
component address space so they can be detached and freed.
