[AArch64][GlobalISel] Fix the LegalityPredicate for lowerIf for G_LOAD/G_STORE
Summary:
Currently, Legalizer is trying to lower G_LOAD with a vector type
that has more than two elements due to the incorrect LegalityPredicate.
This patch fixes the issue by removing the multiplication by 8
as `MemDesc.Size` already contains the size in bits.
