Matthew Stanley 4054dc1c08 fix: DMA ch2 GPU→RAM now reads GPUREAD instead of writing zeros

The VRAM-to-RAM DMA path (channel 2, direction 0) was stubbed to fill
the destination buffer with zeros. This broke all offscreen VRAM
readback — the BIOS shell draws spiral/splash textures to an offscreen
VRAM region, then DMA-transfers the rendered pixels back to RAM for
later use as texture atlas entries. With the stub, all texture buffers
stayed zero, producing invisible button backgrounds.

Fix: call gpu_read_gpuread() for each DMA word instead of writing 0.

Also includes: CDROM GetID two-phase response fix, GPU raw texture
mode fix (opcode bit 0 instead of color==0x808080), debug server
A0/C0 upload history commands with CPU context capture, and extended
write trace ranges.
