Fixes#833
## Description of change
Last couple PRs - such as #820#827#828 - made the native touch hook &
touch injection using `InjectTouchInput` the default path, since it
performs much more reliably with both real touch screens and mouse (or
any other synthetic source).
However, user has reported that WINE lacks `InjectTouchInput` which
means this won't work.
As a fix, revive the old wintouchemu code. Native touch is still the
default, but under following circumstances:
1. if `-touchemuforce` is set, or
2. if any of the required Windows touch APIs are unavailable
then we fail over from native touch to wintouchemu code.
For Linux, condition #2 would be hit during init, and gracefully switch
over.
Caveat: the poke code for IIDX and Nost will continue to require native
touch, I do not want to maintain two paths for this. This means that
iidx poke will stop working on Linux, unfortunately.
## Testing
Tested on Windows with `-touchemuforce` set. This is mostly reverting
Linux code path back to where we were last release, so this should just
work with wine.
