Fix HITMAN 3 boot, layered presentation, and socket imports (#851)

* videoout: synchronize layered flips with premultiplied composition

* shader: support unsigned FFBH subword sources

* shader: apply cube-face result scaling

* shader: prune buffer reads proven out of bounds

* net: implement send and receive exports with shared socket handling
