Fixed wine include detection for Wine > 9.0

[Rossmaxx]

Fixes the issue where building lmms with wine > 9.0 doesn't build remotevstplugin. Thanks @LostRobotMusic for suggesting the change (He actually suggested to fix CmakeCache.txt and I used it as a clue for this fix)

Fixes : #7169

Requesting @PhysSong and @DomClark for reviews.

Fixes : #7169

TODO : Remove old VST include finding code using the macro and replace it fully with paths. Also remove redundant paths. also look into the appimage vst bundling issues.

I feel strongly that hard-coding isn't the way forward here. Diving into the output of ${WINE_CXX} -m32 -v and friends and determining the difference in newer Wine versions is likely the way forward.

I have decided to keep this PR short so as to just fix the missing includes issue. I'll deal with the appimage issue in the future.

I've opened a new PR #7268 which adds -- what I believe to be -- some improvements to FindWine. Unfortunately I'm hitting some roadblocks over there. Help is appreciated.
