aarch64: Fix ZIP1 order in aarch64_expand_vector_init [PR118891]

aarch64_expand_vector_init contains some divide-and-conquer code
that tries to load the odd and even elements into 64-bit registers
and then ZIP them together.  On big-endian targets, the even elements
are more significant than the odd elements and so should come second
in the ZIP.

This fixes many execution failures on aarch64_be-elf, including
gcc.c-torture/execute/pr28982a.c.
