Dipshet 313fd236ee Fix AC6 >1x mosaic and cloud/effects de-swizzle streaks ...

Upscale mosaic. At draw-resolution scale > 1, AC6's deferred
EDRAM restore passes do integer pixel-address math on the PsParamGen
position. Its leftover sub-guest-pixel fraction scrambles into an 8x8
mosaic. Floor the param-gen position (param_gen_integer_guest_position)
and re-add the host sub-pixel at the fetch (param_gen_host_subpixel_restore).
Inert at 1x.

De-swizzle scramble. Some AC6 restore/resample passes
manually de-swizzle the Xenos EDRAM sub-tile layout of their source, which
is only correct on tiled data. The emulator detiles everything to linear,
so the de-swizzle always scrambles, streaking the cloud/effects pipeline.
For allowlisted shader hashes (ac6_neutralize_deswizzle_hashes) the sample
coordinate is replaced with the identity host-texel UV (a 1:1 copy).
