Enable copy dependency between RGBA8 and RGBA32 formats (#5943)

* Enable copy dependency between RGBA8 and RGBA32 formats

* Take packed flag into account for texture formats

* Account for widths not being a multiple of each other

* Don't try to alias depth textures as color, fix log condition

* PR feedback
