Compare aligned size for largest mip level when considering sampler resize (#2306)

* Compare aligned size for largest mip level when considering sampler resize

When selecting a texture that's a view for a sampler resize, we should take care that resizing it doesn't change the aligned size of any larger mip levels.

This PR covers two cases:
- When creating a view of the texture, we check that the aligned size of the view shifted up to level 0 still matches the aligned size of the container. If it does not, a copy dependency is created rather than resizing.
- When searching for a texture for sampler, textures that do _not_ match our aligned size when both are shifted up by its base level are not considered an exact match, as resizing the found texture will cause the mip 0 aligned size to change. It will create a copy dependency view instead.

Fixes graphical errors and crashes (on flush) in various Unity games that use render-to-texture.

* Move shared code to its own method.
