`wasm_loader_push_pop_frame_offset` may pop n operands by using `loader_ctx->stack_cell_num` to check whether the operand can be popped or not. While `loader_ctx->stack_cell_num` is updated in the later `wasm_loader_push_pop_frame_ref`, the check may fail if the stack is in polymorphic state and lead to `ctx->frame_offset` underflow. Fix issue bytecodealliance#2577 and bytecodealliance#2586.
