Compensate for instruction increment when writing to counter CSRs

- Derive RiscVPerformanceCounterCsr{High} from RiscVCounterCsr
- Decrement offset in Set to account for the retiring instruction.
- High::Set handles carry and propagates offset adjustments for high counter CSRs.
- Add unit tests for minstret and minstreth to verify write compensation.
