Fix AArch64 ISel for unpacked types

Using DUP instructions only really works for packed types, as it will
not introduce the spacing between elements that is required for unpacked
types like nxv2f16.

For those, we'll first broadcast to their corresponding packed type, and
then extract the lo lanes into an unpacked type, effectively introducing
the required spacing.
