platform/x86/intel/pmt/telemetry: Add API to retrieve telemetry regions by feature
Introduce a new API, intel_pmt_get_regions_by_feature(), that gathers
telemetry regions based on a provided capability flag. This API enables
retrieval of regions with various capabilities (for example, RMID-based
telemetry) and provides a unified interface for accessing them. Resource
management is handled via reference counting using
intel_pmt_put_feature_group().
