fix: force B8G8R8A8_UNORM swapchain — fixes acid video colors

Browse Source

Root cause: driver returned format=58 (A2B10G10R10_PACK32) as fallback
when B8G8R8A8_SRGB wasn't found. 10-bit packed format has different
byte layout → vkCmdCopyImageToBuffer gives garbage when interpreted as
8-bit BGRA → acid colors in video.

Fix:
- QuerySurfaceFormat: try B8G8R8A8_UNORM first (NVIDIA supports it)
- Fallback: B8G8R8A8_SRGB, then first available
- Removed SRGB LUT conversion — UNORM data is already linear
- Raw BGRA bytes go directly to FFmpeg (pixel_format=bgra)
