[idd] common: use CSRWLock throughout the drivers

Browse Source 
Make CSRWLock own the native lock and provide scoped guards for shared,
exclusive, early-unlock, and non-blocking use.

Replace direct SRW lock management throughout the IDD, input driver,
and helper while preserving the existing lock scopes.
