RSX: Multi-context support [part 1]

[kd-11]

First part of multi-context work. We start by basically refactoring everything into manageable logical units. This refactor focused more on separating the hardware bits but a lot more work is needed in the "thread" since it grew into a monstrosity.
The concept of a hardware context is introduced though currently not used.

#15424

Still WIP, linux/BSD/apple support is not yet ready.

We believe in you, KD-11 ! :)
RSX should be fully and accurately emulated in order to fix remaining issues in PS3 emulation...

@kd-11
That PR is about optimization too ?
Tested not games having slowdown. Several are with same performance, but I see Tekken 5 DR having more 10 % FPS. Need test other games.
Another strange detail with that PR are happening an "rendering ahead" in some games.
For example. Start an game in first screen is the game company logo and second screen the game title. When in first screen being rendered the game company logo in background are being rendered transparent flickering graphics from second screen as if are being rendering ahead in current screen.
Have another users seeing that issue too ?

There should be no visible changes. There are some improvements related to FIFO reordering (optimization) since it was broken before. If you're seeing visual problems let us know, visual output should have remained the same.

Thanks for your reply.
I will clean the RPCS3 cache path and create PPU new modules using that PR and after test with some games.
After post result here.

[Augusto7743]

Cleaned all caches. Created new PPUs modules for that PR build.
Tested in an AMD FX 6300 six core six threads. That cpu is sensitive with PR doing better performance.
Using disable custom vulkan allocator because the GPU is an GT 640 and comparing that setting enabled or disabled is the same performance. Disabling that setting save ram usage.
Games are in ISO format mounted using GCDEMU.

Choplifter HD NPUB30619 when starting in load screen randomly happen the bug "rendering ahead". Before the correct screen loading sequence is showed an screen with flickering graphics from game title in few miliseconds. Hard to do an screenshot.
Related with #15455 ?

Burnout Paradise NPUB30040 has much better performance with that PR. Never before was possible in some moments reach gameplay 100 % speed in AMD FX. Now with that PR run in several moments in 100 % =)
ELEVATOR ACTION DELUXE NPUB30428 are an bit more faster.
Gran Turismo 5 Prologue Spec 3 shaders creation are being smooth compared with previous build. That game does much usage of spus for graphics. Performance is similar with previous build.
MOTORSTORM APOCALYPSE NPUA80661 are an bit more faster.

Other games are with same performance. Perhaps your code in FIFO reordering ?

That PR not does slowdowns. Some games are with better performance and more stable.
Possibly testing in current high end will show an better performance improvement.
The file zip has logs of games above.

THANKS VERY MUCH KD-11 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
YOU HAVE DONE AGAIN !! =)
