2022-01-30perfmon: topdown level 1 and 2 for icxRay Kinsella4-63/+183
Topdown level 1 and 2 for Intel Ice Lake (ICX). Limiting topdown support to THREAD for the moment on Ice Lake, as NODE support is still unreliable. Also removing Topdown Level 1 from Sapphire Rapids onwards, as Topdown LeveL 2 also shows Level 1 on Sapphire, and it reduces the overall number of bundles.

2022-01-30perfmon: fix init of bundles with pseudo eventsRay Kinsella3-18/+41

2021-12-02perfmon: refactor perf metric supportRay Kinsella4-189/+80
Refactoring perf metric support to remove branching on bundle type in the dispatch wrapper. This change includes caching the rdpmc index at perfmon_start(), so that the mmap_page.index doesn't need to be looked up each time. It also exclude the effects of mmap_page.index. This patch prepares the path for bundles that support general, fixed and metrics counters simulataneously.
