rsx/vk: Implement hardware instancing (RPCS3#16466)

* rsx: Add code to detect instanced draw commands

* rsx: Add GLSL support for instanced rendering

* rsx: Move draw call related functions to their own class

* rsx: Move more functions from rsx thread to the draw command processor

* rsx: Fix vertex program compiler crash

* vk: Add support for hardware instanced draws

* rsx: Fix instancing bug when indexed addressing is used to read constants

* rsx: Fix rare crash in vertex program decompiler

- This whole decompiler mess needs a rewrite

* rsx: Handle dangling execution barriers

* rsx: Do not use global registers object in logical "firmware" units

* Cosmetic improvements

* rsx: Test vertex program flags on each draw

* rsx: Properly track changes in instancing state
