  [SVE] Fix selection failure when splitting extended masked loads

When splitting a masked load, `GetDependentSplitDestVTs` is used to get the
MemVTs of the high and low parts. If the masked load is extended, this
may return VTs with different element types which are used to create the
high & low masked load instructions.
This patch changes `GetDependentSplitDestVTs` to ensure we return VTs with
the same element type.
