[SPIRV] Fix vector bitcast check in LegalizePointerCast (#164997)
The previous check for vector bitcasts in `loadVectorFromVector` only
compared the number of elements, which is insufficient when the element
types differ. This can lead to incorrect assumptions about the validity
of the cast.
This commit replaces the element count check with a comparison of the
total size of the vectors in bits. This ensures that the bitcast is
only performed between vectors of the same size, preventing potential
miscompilations.
