[ RFC v2 2/9] target/riscv: pmu: Rename the counters extension to pmu

[Atish Patra]

The PMU counters are supported via cpu config "Counters" which doesn't
indicate the correct purpose of those counters.

Rename the config property to pmu to indicate that these counters
are performance monitoring counters. This aligns with cpu options for
ARM architecture as well.
