[mlir][MemRef] Fix canonicalization of BufferCast(TensorLoad).

CastOp::areCastCompatible does not check whether casts are definitely compatible.
When going from dynamic to static offset or stride, the canonicalization cannot
know whether it is really cast compatible. In that case, it can only canonicalize
to an alloc plus copy.
