Cmake supports finding OpenGL, even if there is no GLX (for glvnd) or
old-style libGL. This change keeps old behavior, but in case, if
X11-related OpenGL libraries cannot be found on Linux, it adds logic
to check for (and link with) libOpenGL, if it is present.
[ChangeLog][QtGui] Allow OpenGL to be found on X11-less Linux systems
(using libOpenGL)

target_link_libraries expects a quoted string like
"-framework CoreFoundation" when linking frameworks and not 2
different arguments like "-framework" "CoreFoundation".
Fix that in the FindWrapOpenGL and FindGLESv2 find modules.
Make sure to not quote the framework link flags when generating
.pri files even if there are spaces, otherwise building apps
with qmake fails.

Our .prl files embedded an absolute path to the OpenGL.tbd file. This
obviously breaks their usage when used on another machine when no SDK
exists.
To fix that we need to use a "-framework OpenGL" linker flag instead
of linking against the absolute path library.
To convince CMake to do that, we have to create a wrapping
OpenGL target which sets an appropriate INTERFACE_LINK_LIBRARIES
property.
So create a FindWrapOpenGL find module to do that on darwin platforms.
Adjust helper.py and our build system to use it.
This tangentially amends 38cd18384f
because it recreates the FindWrapOpenGL module, but for a different
purpose.
