Video core: Fix A4 texture decoding
...
It was trying to take the LSB from `coarse_x`, which would always be 0
and thus would always return the same texel from each byte. To add
insult to the injury, the conditional was actually the wrong way around
too.
Fixes blocky text in OoT.

Video core: Fix pixelation/blockiness in textures.
...
This was caused during morton decoding by me not masking the bits of
each coordinate before merging them, so the bits from x could set bits
in y if it was >255.

GSP: Update framebuffer info on all interrupts
...
Hardware testing determined that the GSP processes shared memory
framebuffer update info even when no memory transfer or filling GX
commands are used. They are now updated on every interrupt, which isn't
confirmed correct but matches hardware behaviour more closely.
This also reverts the hack introduced in #404 . It made a few games
behave better, but I believe it's incorrect and also breaks other games.

Unused OutputVertex attributes were being left un-initialized. The

zeroing the structure we ensure these attributes only contain harmless
zeros.
