[mlir][ArmSME] Add basic lowering of vector.transfer_write to zero
This patch adds support for lowering a 'vector.transfer_write' of zeroes
and type 'vector<[16x16]xi8>' to the SME 'zero {za}' instruction [1],
which zeroes the entire accumulator, and then writing it out to memory
with the 'str' instruction [2].
This contributes to supporting a path from 'linalg.fill' to SME.
