* [VideoOut] Prefer real integrated GPUs over software rasterizers (#325)
Penalize only AMD integrated GPUs (the #97 vkCreateGraphicsPipelines
crash) instead of all integrated devices, so Intel/Apple/Qualcomm iGPUs
outrank Cpu-type software rasterizers (Mesa lavapipe). Hoist
ScorePhysicalDevice to the outer class and add unit tests for the
ordering.

* [VideoOut] Scope AMD iGPU penalty to Windows via a penalty helper
Extract ComputeDevicePenalty (the value subtracted from a device's base
score) and gate the #97 AMD-integrated penalty on Windows only. Mesa RADV
on Linux (e.g. the Steam Deck's AMD APU) is a different, working driver
and should keep its full integrated score. Add a Steam Deck test case and
drop inline comments.

* [VideoOut] Move device-scoring helpers out of the const block
Relocate ScorePhysicalDevice and ComputeDevicePenalty below the leading
const cluster instead of splitting it, and trim the vendor-ID reference
comment to adapters an x86-64 host can realistically enumerate.

Changes MapPixelFormatToGuestTextureFormat to default to format 56 (8-bit
RGBA) when the game uses a pixel format not yet in the known list, with a
stderr warning that reports the exact format value for project issue reports.
Previously, unknown formats returned 0, which caused RegisterKnownDisplayBuffer
to skip registration entirely. The GPU backend then couldn't find the buffer
during flip, producing vk.flip_capture_failed, and some games later hit a
Debug.Assert in ExecuteOrderedGuestFlipWait.
The fallback produces wrong colors for the affected games but lets them render
and display output, which is strictly better than a black screen or access
violation crash. The pixel format is printed to stderr so developers can
identify it and add proper support.
