Use 8 bit mode if available

This was not previously done because the palette was not correctly set
up, and QEMU gave incorrect colors. The palette setup function now
falls back to the standard BIOS function if the VESA BIOS function
fails, which resolves the issue with QEMU. The mode selection logic now
favors 8 bit color if the tile set is compatible.

Using 8 bit mode means fewer writes to memory and fewer uses of the
BIOS window function.
