GPU: Move the hardware backends' matrix commands up to GPUCommon
...
So a backend that isn't GPUCommonHW can use them. No change in behaviour.

GPU: Rasterize software depth on a worker thread
...
The depth draws were queued and rasterized on the emu thread at each render target change, in
Wipeout about 40 small batches a frame, and around 40% of that thread's time. Now a render target
change hands the batch to a worker thread and carries on. Waiting for it is left to whatever reads
the depth buffers: DrawSync and ListSync, block transfers, framebuffer copies, showing a frame,
savestates and shutdown, and the texture cache when the texture or CLUT it reads overlaps a depth
buffer still being written.
Batches grow as needed instead of being preallocated at full size. A full batch is now handed over
and a new one started, where the draw used to be dropped.
Wipeout headless, output unchanged: 16% less wall time on a Galaxy S8 (8.2 s to 6.9 s for 10
emulated seconds). On an M1, where headless waits on the GPU, the emu thread uses 38% less CPU time.

Finish the split. Greatly simplifies the render code in EmuScreen.

Cache framebuffer copies (for self-texturing) until the next TexFlush instruction.
...
Fixes #17030 , or at least improves on it - for optimal performance that
big framebuffer used for bloom should be split like in Killzone, but it's not trivial.
The regression in 1.14 is fixed with this, at least.
I tried it with a few other games with no issues - it seems games are
using TexFlush when needed. But let's see if it really is safe to rely
on that...
There might also be other places we should call DiscardFramebufferCopy
in.
