[PATCH] Add VXRM enum

[PATCH] Add VXRM enum

[chenyixuan]

From: XYenChi <chenyixuan@iscas.ac.cn>

Noticed that the rvv-intrinsic-doc updated the __RISCV_VXRM.
gcc/ChangeLog:Add __RISCV_VXRM enum to riscv_vector.h

2023-07-13  XYenChi  <chenyixuan@iscas.ac.cn>

        * config/riscv/riscv_vector.h (enum __RISCV_VXRM):Add an enum __RISCV_VXRM to help express the rounding modes.

We have that already in riscv-protos.h :)

Those enum values have been defined via `#pragma riscv intrinsic "vector"` :)
