Skip YUV texture dumping

[nexus382]

###What I changed / why

FMV stuff was blasting the texture dump folder with tons of throwaway frames.
-I added a small guard so texture dumping skips YUV textures, since those are typically the video frames.

• Added toggle to "DISABLE YUV DUMPING" and added a description of what EXACTLY it is doing.

###Result
-Normal texture dumping stays on.
-YUV (video) textures don’t get dumped, so FMVs don’t spam the dump folder or make things choppy.

###Notes
-This is a simple, targeted tweak in the texture dump path.

###TO DO
Add toggle [ X ]

Unintended bonus: Any FMV that has YUV flag activate, HAS NO JITTER when watching and dump is on. This makes FMV's so hard to watch and imerse in, but now, ou can dump, and enjoy your YUV FMVs smooth as butter.

UPDATE

Have been testing this, Every game I play I will dump with this on, and off, and so far, I have not noticed any missing USEABLE textures. It has caught every FMV so far, and we have done comparative testing where I have noticed some garbage textures "not dumping" but I am not sure if this is due to this, as they seem random when the trash dumps happen, so it is not a reliable dumped texture, adn randomly dumps at random times in most cases.

But the label currently is factual, and also shows intent, Without claiming anything not 100% fact.

WILL KEEP UPDATING AS I TEST FURTHER.
