  MythWelcome: Pass the Qt QPA platform through to mythfrontend

- if it has not been explicitly set by the user already
- in mosts cases, this will have no impact but with many current Wayland
desktops, Qt has to be encouraged to use Wayland over xcb (even when
there is no X11). In these cases, we need to then ensure that the
mythfrontend instance launched by mythwelcome has the appropriate
platform

  Wayland: Add workaround for invisible windows...

- Qt 5.11.2 works, Qt 5.14.2 is broken. I'm not sure when it was broken
and if it has subsequently been fixed... but here's the explanation...
- on newer versions of Qt when using Wayland and the xdg-shell
integration (and its variants), our painter window's window
(MythPainterWindow is a widget - which has a window) does not receive an
expose event on startup.
- as a result, calls to MythPainterWindow::update (called from
MythMainWindow::animate) do not result in paintEvent calls being
delivered and we get a blank screen
- this is easily identifiable by checking whether the window is visible
and not exposed (note - we only start checking once we have received a
resizeEvent, which should imply MythPainterWindow itself is visible)
- use a QTimer to start checking - and once the issue appears to be
fixed, stop the timer (note - I'm not sure whether the check should
continue or maybe restarted following a visibility change?)
- the issue is avoidable by forcing Qt to use a non xdg-shell - but the
other shell variants are slowly being deprecated as the xdg-shell spec
is finalised.

Refs #266 (but this does not fix it)
