[PATCH 0/2] MR7282: winemac: Fix issues found with Main Thread Checker

[Brendan Shanks (＠bshanks)]

Fix 3 calls to AppKit that were not being done from the main thread, found using Apple's [Main Thread Checker](https://developer.apple.com/documentation/xcode/diagnosing-memory-thread-and...).

I used it with Wine by dlopen()ing `/Applications/Xcode.app/Contents/Developer/usr/lib/libMainThreadChecker.dylib` in `macdrv_init()`, commenting out the `SIGABRT` handler in `signal_x86_64.c`, and setting `MTC_CRASH_ON_REPORT=1` so the process will `abort()` and eventually generate a crash log+backtrace.
