platform/x86/intel/pmt/discovery: Get telemetry attributes
Add intel_pmt_get_features() in PMT Discovery to enable the PMT Telemetry
driver to obtain attributes of the aggregated telemetry spaces it
enumerates. The function gathers feature flags and associated data (like
the number of RMIDs) from each PMT entry, laying the groundwork for a
future kernel interface that will allow direct access to telemetry regions
based on their capabilities.
