Make QT_WAYLAND_COMPOSITOR_QUICK a feature
The define was only set when building Qt, not when including public
headers in application code. Therefore, the sizes of objects did not
match between the client code that calls new and the constructor inside
Qt.
Unfortunately, adding the additional members breaks binary
compatibility. This has already happened between 5.11 and 5.12. It just
wasn't apparent from the headers. If we removed the members again now,
we would break binary compatibility again. Therefore, the best course of
action seems to be acknowledging the break and adding the members also
in the headers.
[ChangeLog][Compositor][Important Behavior Changes] Between
version 5.11 and 5.12 binary compatibility for the wayland compositor
module was broken by adding an additional member to various classes.
This was not apparent from user code as the member was behind an #ifdef
which would only be set while compiling Qt. As several versions of Qt
incompatible to 5.11 have already been released now, rolling back the
incompatible change would introduce further incompatibility. Therefore,
the change is made consistent by unconditionally adding the member to
the headers.
