Subject: shiboken2/clang: Write scope resolution for all parameters of native
 wrappers

Make sure types are correct for cases like:

- QtDBusHelper::QDBusReply::QDBusReply(::QDBusReply<void>)
- Qt3DInput*Event constructors taking the equivalent QtGui classes
  (Qt3DInput::QMouseEvent(::QMouseEvent *);

[ChangeLog][shiboken6] Support for parameters/function return
types with scope resolution has been improved.

Fixes: PYSIDE-2288
Pick-to: 6.5 5.15
Change-Id: Id29758fceb88188f4cd834fbd5a7cc0ab511fb1a
