Alexander Shishkin 28c24ded64 perf/x86/intel/pt: Add a capability and config bit for event tracing
As of Intel SDM (https://www.intel.com/sdm) version 076, there is a new
Intel PT feature called Event Trace which is enabled config bit 31.

Event Trace exposes details about asynchronous events such as interrupts
and VM-Entry/Exit.

Add a capability and config bit for Event Trace.
