[PyQt] Dlls Missing from Windows Wheels

[Cody Scott]

While looking at a PyInstaller AppVeyor build[0] I noticed that there are
missing dependencies for qtquickscene3dplugin.dll and
qtquickscene2dplugin.dll.

Here is the output.

Analyzing

The code PyInstaller uses to find missing dependencies appears to be
here[1].

So the missing .dll files from the Windows wheels are:

- Qt53DRender.dll
- Qt53DInput.dll
- Qt53DCore.dll
- Qt53DLogic.dll
- Qt53DQuickScene2D.dll

I found addition files by using dependency walker[2] on those files (from
Qt 5.10.0) there are some more files missing from the Windows wheels:

- Qt5Concurrent.dll (required by Qt53DRender.dll)
- Qt5GamePad.dll (required by Qt3DInput.dll)
