target/arm: Share unallocated_encoding() and gen_exception_insn()

The unallocated_encoding() function is the same in both
translate-a64.c and translate.c; make the translate.c function global
and drop the translate-a64.c version.  To do this we need to also
share gen_exception_insn(), which currently exists in two slightly
different versions for A32 and A64: merge those into a single
function that can work for both.

This will be useful for splitting up translate.c, which will require
unallocated_encoding() to no longer be file-local.  It's also
hopefully less confusing to have only one version of the function
rather than two.
