Warn if providing explicit bindings to a object using uniform locations (#4708)
fixes: #4700
Changes:
* If a uniform object (which uses uniform locations) has explicit bindings we will warn to use `ConstantBuffer<T>` instead. We check for a warning specifically when we know an object uses uniform layouts because objects may not use a uniform-layout register even if tagged with `uniform`. A good example of this is `uniform ConstantBuffer<T>`.
