tdf#148864 Qt switch QtObjectWindow to QWidget

... and therefore rename it to QtObjectWidget

Replacement of the QWidget with QWindow originally happened in
commit 56b19f9a814ae5a39ed760ee542d715493cd0bf3 ("tdf#121247,
tdf#121266 KDE5: Add basic support for OpenGL"), but that
unfortunately has a very sparce commit message with no reason
for this change. Then the code was further complicated in commit
25edbded9946801effd117b9c46de0f8b4bc5632 ("tdf#125517 Qt5
implement a minimal Qt5ObjectWindow") and a few follow up fixes
to restore input and focus handling.

But appearingly all this QWindow handling isn't necessary and just
returning to a QWidget based class fixes the problems with the
video overlay (AKA QWidget::winId()) and video playback for good.

The OpenGL Impress transition (Fade) mentioned in the original
tdf#121266 bug still works.

This also adds the previously missing SolarMutexGuard to all the
overridden QtObjectWidget functions, which call the SalObject's
Callback function. I accidently triggered a DBG_TESTSOLARMUTEX
crashing Impress while debugging this.
