[AArch64][GlobalISel] Fix matchUseVectorTruncate to check element order before folding (#185834) ...

matchUseVectorTruncate incorrectly folded a
G_UNMERGE_VALUES + G_TRUNC + G_BUILD_VECTOR sequence into a single
vector G_TRUNC even when the BUILD_VECTOR operand order did not match
the UNMERGE_VALUES result order. This silently dropped element
reordering, producing a miscompile.

Add an element-ordering check: BUILD_VECTOR position I must use
UNMERGE_VALUES result I, otherwise the fold is rejected.
