tools/power turbostat: Add MTL's PMT DC6 builtin counter
 
Provide a definition for metadata that allows reading DC6 residency
counter via PMT and exposes it as a builtin counter.

Note that this residency counter is updated and read via
entirely different mechanisms vs the MSR-based residency counters.
On MTL processors, there are times when Die%c6 will report above 100%.
This is still useful, but don't expect 3 digits of precision...
