loveplus: stub impl of cpusbxpkm.dll (printer) (#319)

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

## Description of change
Add a stub for `cpusbxpkm.dll`. The stub doesn't work, it's only enough
to allow the game to load; but that is irrelevant since spice hooks the
printer at runtime.

## Testing
Observed the game boot, and was able to print out the test image from
test menu. Will do more testing on a real server.
