[AArch64][SVE] Asm: Support for reversed subtract (SUBR) instruction.

Description

[AArch64][SVE] Asm: Support for reversed subtract (SUBR) instruction.

This patch adds both a vector and an immediate form, e.g.

  • Vector form:

    subr z0.h, p0/m, z0.h, z1.h

    subtract active elements of z0 from z1, and store the result in z0.
  • Immediate form:

    subr z0.h, z0.h, #255

    subtract elements of z0, and store the result in z0.
