[Bug 1876528] Re: Add patch for variable KWIN_USE_INTEL_SWAP_EVENT

[xalt7x]

@scarlettmoore.
Thanks for reaching out. I believe it was meant to optimize VSync on KWin
Eventually, KWin upstream developers had set KWIN_USE_INTEL_SWAP_EVENT environment variable by default, but then reverted it due to performance issues (https://invent.kde.org/plasma/kwin/-/merge_requests/627). After that KWin, compositor underwent a major refactoring, so I believe those patches shouldn't be applied anymore, and this bug can be closed.
