Now that KVM disables vPMU support on hybrid CPUs, WARN and return zeros
if perf_get_x86_pmu_capability() is invoked on a hybrid CPU. The helper
doesn't provide an accurate accounting of the PMU capabilities for hybrid
CPUs and needs to be enhanced if KVM, or anything else outside of perf,
wants to act on the PMU capabilities.

From the perspective of Intel cstate residency counters,
Emerald Rapids is the same as the Sapphire Rapids and Ice Lake.

From core PMU's perspective, Emerald Rapids is the same as the Sapphire
Rapids. The only difference is the event list, which will be
supported in the perf tool later.

Meteor Lake is Intel's successor to Raptor lake. From the perspective of
Intel cstate residency counters, there is nothing changed compared with
Raptor lake.
Share adl_cstates with Raptor lake.
Update the comments for Meteor Lake.

Since Tigerlake seems to have inherited its cstates and other RAPL power
caps from Icelake, assume it also follows Icelake for its RAPL events.
