aarch64: Add more vector permute tests for the FMOV optimization [PR100165]

This patch adds more tests for vector permutes which can now be optimized as
FMOV with the generic PERM change and the aarch64 AND patch.

Changes since v1:
* v2: Add -mlittle-endian to the little endian tests explicitly and rename the
tests accordingly.
