[mlir][vector] Add insertOp src shape check for BubbleUpBitCastForStridedSliceInsert

Not all shape of vectors can be casted into other types, we add a check
to not fold insertOp into bitcast if the shape does not support it.

Examples of unsupported shape castings are f16 vectors to f32 if the
shape is not multiple of 2s. or int8 to int32 if shapes are not multiple
of 4.
