Separate GPU engines (part 2/2) (#2440)

* 3D engine now uses DeviceState too, plus new state modification tracking

* Remove old methods code

* Remove GpuState and friends

* Optimize DeviceState, force inline some functions

* This change was not supposed to go in

* Proper channel initialization

* Optimize state read/write methods even more

* Fix debug build

* Do not dirty state if the write is redundant

* The YControl register should dirty either the viewport or front face state too, to update the host origin

* Avoid redundant vertex buffer updates

* Move state and get rid of the Ryujinx.Graphics.Gpu.State namespace

* Comments and nits

* Fix rebase

* PR feedback

* Move changed = false to improve codegen

* PR feedback

* Carry RyuJIT a bit more
