[binutils][aarch64] New SVE_SHRIMM_UNPRED_22 operand.
Include a new iclass to extract the variant from the most significant 3
bits of this operand.
Instructions such as rshrnb include a constant shift amount as an
operand, where the most significant three bits of this operand determine
what size elements the instruction is operating on.
The new SVE_SHRIMM_UNPRED_22 operand denotes this constant encoded in
bits 22:20-19:18-16 while the new sve_shift_tsz_hsd iclass denotes that
the SVE qualifier is encoded in bits 22:20-19.
