When DLL is configured to use LDJ I/O but spice is in TDJ mode, show an
error in TDJ overaly suggesting the user to fix the DLL.
Fix a small bug that caused a white window to be created when `-w` is
enabled even when `-iidxtdj` is not, but DLL is using TDJ I/O.

## Description of change
In the main menu (Esc key), instead of just saying `Show subscreen`,
detect game and say `Show TDJ Subscreen` `Show LDJ LED Ticker` etc.
For the LED ticker window, show the title bar by default, and add an
option to hide it back.
This is to help with cases where people get stuck with being in LDJ mode
when they meant to turn on TDJ.
## Testing
Tested all configurations (IIDX LDJ/TDJ, SDVX UFC, DRS)
