rocr/driver: move wallclock frequency query to driver layer

Browse Source 
Move the wallclock frequency query from GpuAgent to driver layer to improve
code organization and support multiple driver types. This change:

1. Add GetWallclockFrequency API to KFD/XDNA drivers
2. Move libdrm GPU info query from GpuAgent to driver implementation
3. Update GpuAgent to use the new driver API
