Change image format view handling to allow view incompatible formats (#7311)
* Allow creating texture aliases on texture pool

* Delete old image format override code

* New format incompatible alias

* Missing bounds check

* GetForBinding now takes FormatInfo

* Make FormatInfo struct more compact
