rsx: Minor fixes

[kd-11]

• Allow shader binding points to alias in the GL binding map. This is annoying, but old hw can have low amount of allowed resources (e.g only 8 SSBO slots)
• Fix linear cubemap decoding when the face size is very small. Mistake from misinterpreted hwtest, I had swizzling enabled when I ran it many years ago, turns out behaviour is different depending on whether padding is enabled or not.

Fixes #10973
Fixes #9588
Fixes #10458
Fixes #8420

Probably fixes more, needs testing.

Torchlight shadow cubemaps fixed :)

Spotlight flashing lightbulb shadow cubemaps still broken:

(maybe the same fix is required for this type shadowmaps ?)

[kd-11]

RSX emulation is mostly LLE, so there is no cubemap fix per-se, just a fix in hardware emulation. These games aren't even using cubemaps for shadowing, just for address translation. Shadowing is done using virtual cubemaps - a thing that nvidia pushed back in the day due to hardware deficiencies in their products. As such, if you see issues in some other type of light, it will need a different fix. Just open a different ticket for that.
