gb: boot ROM (BIOS) support
Add optional boot ROM emulation. When a boot ROM image is loaded, gb_reset
starts execution at PC=0 with power-on register state instead of the
documented post-boot state; the ROM overlays low memory (with the CGB
0x0100-0x01FF header hole showing the cartridge through) until the game
writes 0xFF50 to hand off. gb_load_bootrom() accepts 256-byte (DMG) or
2304-byte (CGB) images.
