  [AArch64] Implement promotion type legalisation for histogram intrinsic (#101017)

Currently the histogram intrinsic
(llvm.experimental.vector.histogram.add) only allows i32 and i64 types
for the memory locations to be updated, matching the restrictions of the
histcnt instruction. This patch adds support for the legalisation of
smaller types (i8 and i16) via promotion.
