* Add internal render resolution scale and fix embedded surface DPI scaling
Adds a GUI-configurable internal resolution scale (Graphics tab) that
renders offscreen color/depth targets below native guest resolution
and upscales on present, trading image quality for GPU headroom.
Storage/UAV images and sampled asset textures are left untouched, and
texture-alias/feedback-loop lookups compare against each target's
logical (unscaled) size so scaled render targets are still found
correctly when sampled back.
Also fixes the embedded game surface not filling the window: the
isolated emulator child process had no declared DPI awareness, so
Windows silently downscaled every window-geometry query it made
against the GUI-owned surface HWND by the display's DPI factor,
leaving an unfilled black margin on scaled displays.
