  Log Message:
  -----------
  [mlir][ArmSME] Add initial dialect with 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.

This contributes to supporting a path from `linalg.fill` to SME.
