An 'arith.constant dense<0>' is currently lowered to 'arm_sme.zero' as
part of the 'vector.transfer_write' lowering during '-vector-to-arm-sme'
conversion. This patch makes this lowering independent of the
'vector.transfer_write'. This can then be extended for further tile
types and non-zero constants.
