fix: BMG returns non-zero maxClockRate in zeDeviceGetMemoryProperties

Browse Source 
Implemented getDeviceMemoryMaxClkRate() override for BMG Linux to query
actual memory clock rate from DRM driver instead of returning 0.

Updated unit test to dynamically verify maxClockRate matches ProductHelper
return value instead of expecting hardcoded 0.
