Image subresources barriers (#904)

* video_core: texture: image subresources state tracking

* shader_recompiler: use one binding if the same image is read and written

* video_core: added rebinding of changed textures after overlap resolve

* don't use pointers; slight `FindTexture` refactoring

* video_core: buffer_cache: don't copy over the image size

* redundant barriers removed; fixes

* regression fixes

* texture_cache: 3d texture layers count fixup

* shader_recompiler: support for partially bound cubemaps

* added support for cubemap arrays

* don't bind unused color buffers

* fixed depth promotion to do not use stencil

* doors

* bonfire lit

* cubemap array index calculation

* final touches
