Lift textures in the AutoDeleteCache for all modifications. (#2615)
* Lift textures in the AutoDeleteCache for all modifications.

Before, this would only apply to render targets and texture blit. Now it applies to image stores, the fast dma copy path and any other type of modification.

Image store always at least has one reference in the texture pool, so the function of the AutoDeleteCache keeping textures _alive_ is not useful, but a very important function for a while has been its use to flush textures in order of modification when they are dereferenced, so that their data is not lost.

Before, textures populated using image stores were being dereferenced and reloaded as garbage. Now, when these textures are dereferenced, their data will be put back into memory, and everything stays intact.

Fixes lighting breaking when switching levels in THPS1+2, and potentially some more UE4 games. I've tested a bunch more games for regressions and performance impact, but they all seem fine.

* Lift copy srcTexture so that it doesn't remain referenceless

* Perform lift before reference count change on unbind.

It's important to lift on unbind as that is the moment the texture was truly last modified, but definitely not after releasing every single reference.

Avoid deleting textures when their data does not overlap. (#2601)
* Avoid deleting textures when their data does not overlap.

It's possible that while two textures start and end addresses indicate an overlap, that the actual data contained within them is sparse due to a layer stride. One such possibility is array slices of a cubemap at different mip levels - they overlap on a whole, but the actual texture data fills the gaps between each other's layers rather than actually overlapping.

This fixes issues with UE4 games having incorrect lighting (solid white screen or really dark shadows). There are still remaining issues with games that use the 3D texture prebaked lighting, such as THPS1+2.

This PR also fixes a bug with TexturePool's resized texture handling where the base level in the descriptor was not considered.

* AllRegions granularity for 3d textures is now by level rather than by slice.

* Address feedback

Remove pool cache entries for incompatible overlapping textures (#2568)
This greatly reduces memory usage in games that aggressively reuse memory without removing dead textures from the pool, such as the Xenoblade games, UE3 games, and to a lesser extent, UE4/unity games.

This change stops memory usage from ballooning in xenoblade and some other games. It will also reduce texture view/dependency complexity in some games - for example in MK8D it will reduce the number of surface copies between lighting cubemaps generated for actors.

There shouldn't be any performance impact from doing this, though the deletion and creation of textures could be improved by improving the OpenGL texture storage cache, which is very simple and limited right now. This will be improved in future.

Another potential error has been fixed with the texture cache, which could prevent data loss when data is interchangably written to textures from both the GPU and CPU. It was possible that the dirty flag for a texture would be consumed without the data being synchronized on next use, due to the old overlap check. This check no longer consumes the dirty flag.

Please test a bunch of games to make sure they still work, and there are no performance regressions.
