Windows driver: simplify TCSleep to use KeDelayExecutionThread

Browse Source 
Replace timer-based TCSleep (which allocated a KTIMER and waited on it) with an
implementation that calls KeDelayExecutionThread. This removes dynamic allocation
and kernel timer usage to simplify the code and reduce resource overhead.
Adds an IRQL <= APC_LEVEL assertion and documents the requirement.

This is safe because TCSleep is always called from code that runs at PASSIVE_LEVEL
