The WS_EX_LAYERED state of a window can be determined on creation, and
the logic to do so should be centralized to QWindowsWindow::setWindowLayered,
so that we don't have divergence.
This fixes an issue where child windows would only support transparency
if they had Qt::FramelessWindowHint set, as the QWindowBackingStore had
a different idea about when to enable WS_EX_LAYERED than QWindowsWindow.

The lack of WS_CLIPCHILDREN will cause drawing artifacts, so ensure
we have WS_CLIPCHILDREN in our native window manual tests, and warn
if users inadvertently end up reparenting windows into a HWND that
doesn't have WS_CLIPCHILDREN set.

When a native/foreign window is used as a parent, its WS_CLIPSCHILDREN
style should be enabled. If it is not, the parent will paint on top of
the children and cause flickering. It is not Qt's responsiblity to
adjust the styles of foreign windows, so instead we document this in the
manual test.

Update the manual test case for embedded windows to have
native window on Android.
There are still some sharp corners, for example:
* The windows are implemented with SurfaceViews, which makes
z-ordering with multiple of them a bit tricky. The Surfaces
they instantiate are basically z-ordered to either be below
everything, with a hole punched in the window, or on top of
everything, with the Surfaces created later on top of the
ones created earlier. Also, with the foreign views it looks
like the native view is on top of the Surface, because it
is created later. And since the child windows create their
Surfaces before the parent, they would be behind the parent
window, currently circumventing this with letting the
parent be z-ordered behind everything, and the children
on top of everything. A follow up commit addresses this by
changing the native view class to TextureView when multiple
windows are present.
* Parent window always gets the touch events - fixed in
a follow up commit
* If a child window has a text edit, it does not receive
focus when clicking on it

QWindow::setMask() is not guaranteed to turn the masked out areas
transparent, and it's up to the client to ensure this during
painting.

For the child windows we have to use showNormal() explicitly,
as the default window state logic of platforms like iOS does
not have access to the QWindow, only to its flags, and we
can not use Qt::SubWindow as a proxy for being a child window,
as that's a window flag meant to be used for MDI sub windows.
