Henrik RydgårdandClaude Opus 5.5 987a904cff Metal: Fail backbuffer readbacks until something draws to it ...

Headless renders to an offscreen backbuffer that nothing ever draws to,
so the GE debugger's screenshot read uninitialized memory. Fail the
readback instead, like headless Vulkan (which has no backbuffer), so the
debugger falls back to the displayed PSP framebuffer.

All the GE debugger buffers (screenshot, render color/depth/stencil,
texture, CLUT) now read back the same as Vulkan's.
