[RISCV] Bump hwprobe support to Linux 6.11 (#108578)
This patch is the follow-up of
https://github.com/llvm/llvm-project/pull/94352 with some updates:
1. Add support for more extensions for `zve*`, `zimop`, `zc*`, `zcmop`
and `zawrs`.
2. Use `RISCV_HWPROBE_KEY_MISALIGNED_SCALAR_PERF` to check whether the
processor supports fast misaligned scalar memory access.
https://github.com/llvm/llvm-project/pull/108551 reminds me that the
patch
https://lore.kernel.org/all/20240809214444.3257596-1-evan@rivosinc.com/T/
has been merged. Address comment
