perf/x86/intel/pt: Add support for address range filtering in PT
Newer versions of Intel PT support address ranges, which can be used to
define IP address range-based filters or TraceSTOP regions. Number of
ranges in enumerated via cpuid.
This patch implements PMU callbacks and related low-level code to allow
filter validation, configuration and programming into the hardware.
