rocr/driver: add PC sampling support to driver interface

Browse Source 
Add PC sampling functionality to the driver interface:

1. Add new PC sampling methods to Driver base class:
   - PcSamplingQueryCapabilities
   - PcSamplingCreate
   - PcSamplingDestroy
   - PcSamplingStart
   - PcSamplingStop

2. Implement PC sampling methods in KfdDriver using HSAKMT APIs:
   - Map HSAKMT status codes to HSA status codes
   - Handle resource busy conditions
   - Proper error handling for all operations
