// __settile_col
// Copy `len` successive tile numbers from `src` vertically, starting at `(x,y)` in the
// LCDC-selected BG map. The source advances one byte and the destination 32 bytes per
// tile. Waits for writable VRAM when necessary. The LCD-on path uses interrupt masking
// and can enable interrupts afterward; it is not a promise to preserve the caller's
// interrupt state or to finish within one VBlank.
// Expected: FAILED CHECKS 000, with the written tile data in the selected map.
