Pending feedback resources (cmds, buffers, slots) for timeline semaphores are
generally reclaimed for re-use during subsequent semaphore waits/queries or any
queue submission containing at least one "wait" semaphore.
They are never reclaimed in the unexpected case when all submissions only
contain "signal" timeline semaphores, which consume such resources but
are never subsequently queried or waited upon.
This strange behavior is observed in several Valve games (Portal 2,
L4D2, CS2), which all run natively on linux with their own internal
distributions of DXVK v2.0 (at time of this MR submission). A Cursory
analysis of recent DXVK history indicates that it may be gone by v2.1.
The consequence is rapid guest memory leak and host Vk resource leak,
resulting in a crash within 1-2 minutes.
Fix that leak by running the reclaimation procedure for submissions with
_any_ accompanying semaphores.
