GS/HW: Implement RT in RT support

[refractionpcsx2]

Description of Changes

Adds support for render target inside render target draws and shuffles, where games point to an offset inside a previously drawn target, usually to update single pages, or offset half way through a picture.

Rationale behind Changes

We didn't support this and relied on exact start address matches, and a bunch of games do it.

Suggested Testing Steps

Test games which had "top left corner" bugs or weird half screen problems.

Known to fix:
Battlefield 2 - Fixes things the CRC hack was chopping out, also required fixing how sources get invalidated
Big Mutha Truckers - No longer requires a CRC hack for half screen shuffle
Call of Duty - World at War - Final Fronts - lighting closer matches software
Conflct Desert Storm - Flickering fixed
Death by Degrees - lighting and fog effects post processing (top left corner) are fixed (CRC can be removed)
Delta Force - Black Hawk Down - Fixes player 2 night vision
Drakengard - Post shuffle effect on death
Driv3r - Doesn't need such a cacophony of fixes, just CSBW 4/2 + Tex in RT, plus fixes the sun glares.
Haunting Ground - Quite possibly no longer needs CRC hack
Hitman Blood Money - Post processing and shadows fixed (still needs CRC for weird corner uploading thing, but may be more fixable these days)
Hitman Contracts - Graphics completely fixed
Ghost in the Shell - Stand Alone Complex - No longer requires CRC hack and fixes channel shuffle
Jak X - Combat Racing - Player 2 now visible
Peter Jackson's King Kong- The Official Game of the Movie - pretty much fixed with rt in rt
Manhunt 2 - Post Process (top left corner) lighting fixed
Onimusha - Warlords - fmvs seem to not flicker (game currently uses SW FMV)
Ridge Racer V - Less hacks required, intro can now be upscaled
Sniper Elite - Second player lighting overlay fixed
Stolen - All graphics processing is fixed, lighting, etc. Speed is also not terrible
Spiderwick Chronicles - Half screen problem in book fixed
Suikoden III - Half screen black and white effect fixed
SWAT - Global Strike Team - Player 2 colours corrected
Taiko no Tatsujin Bang Tap - Lighting overlay (top left corner) fixed
Tekken 5 - Fire effect can now be used upscaled and half screen fire effect problem is fixed
TOCA Race Driver 2 - shadows fixed
Time Crisis 3 - Post processing looks correct now
Tomb Raider - Legends - Fixes for post lighting effects not covering the screen in some levels and goggles
Wild Arms 5 - No longer requires Framebuffer Conversion hack ,meaning sepia scenes now upscale properly
Wrath Unleashed - Fixes colours
WRC 3 - Half screen fog effect fixed.

Improves but doesn't currently fix:
Pachipara
Raw Danger
Steambot Chronicles

All the above games will likely need a further CRC to fix the remaining issues due to a weird shuffle and manual deswizzling of depth.

Note: This is gated behind Tex in RT and will break some games if left on, be it on your own head!
