video_core: Add depth buffer support and fix some bugs (#172)

Browse source 
* memory: Avoid crash when alignment is zero

* Also remove unused file

* shader_recompiler: Add more instructions

* Also fix some minor issues with a few existing instructions

* control_flow: Don't emit discard for null exports

* renderer_vulkan: Add depth buffer support

* liverpool: Fix wrong color buffer number type and viewport zscale

* Also add some more formats
