mfc: fix 2025 version touch (#426)

## Link to GitHub Issue, if one exists
n/a

## Description of change
HG cabinet uses wintouch and it requires TOUCHEVENTF_PRIMARY flag in
order to accept touch inputs.
Added wintouchemu on game hook and TOUCHEVENTF_PRIMARY flag on
wintouchemu.
 
## Testing
The game boots into test menu, touch now works. (tested in I/O TEST ->
TOUCH PANEL CHECK with '-s' flag)
TDJ subscreen overlay and nostalgia seems works fine regardless added
TOUCHEVENTF_PRIMARY flag but more testing required.
