[Name of user not set (Code Review)]

Hello Patrick Rudolph, ron minnich, build bot (Jenkins), Nicolas Reinecke, Patrick Georgi, Martin Roth,

security/intel/stm: Check for processor STM support

This check ensures that the current processor supports a STM.
Normally, any Intel x86 processor that has VTx also supports
an STM and this check should fail only in the rare case that STM
support has been disabled for a processor.
