perf/x86/intel: Introduce the fourth fixed counter
The fourth fixed counter, TOPDOWN.SLOTS, is introduced in Ice Lake to
measure the level 1 TopDown events.
Add MSR address and macros for the new fixed counter, which will be used
in a later patch.
Add comments to explain the event encoding rules for the fixed counters.
