perf/x86/intel: Add PMU support for ArrowLake-H
ArrowLake-H contains 3 different uarchs, LionCove, Skymont and Crestmont.
It is different with previous hybrid processors which only contains two
kinds of uarchs.
This patch adds PMU support for ArrowLake-H processor, adds ARL-H
specific events which supports the 3 kinds of uarchs, such as
td_retiring_arl_h, and extends some existed format attributes like
offcore_rsp to make them be available to support ARL-H as well. Althrough
these format attributes like offcore_rsp have been extended to support
ARL-H, they can still support the regular hybrid platforms with 2 kinds
of uarchs since the helper hybrid_format_is_visible() would filter PMU
types and only show the format attribute for available PMUs.
