inteltool: Add support to print TME/MKTME status

Browse Source 
Print whether the SOC supports TME/MKTME. If the SOC supports the
feature, print the status of enable and lock bit from TME_ACTIVATE
MSR. -t option prints this status.

Sample output:

If TME/MKTME is supported:
============= Dumping INTEL TME/MKTME status =============
TME supported : YES
TME locked    : YES
TME enabled   : YES
====================================================

If TME/MKTME is not supported:
============= Dumping INTEL TME status =============
TME supported : NO
====================================================
