Subject: Enable support for OpenVG

This commit re-enables support for OpenVG in Qt, but not in the
same way as in Qt 4.8.  The first part is about adding a test
and using the new configure system to enable OpenVG.

There is still support code in Qt for setting up EGL to provide a
surface and context for rendering with the OpenVG API, this commit
enables a path to do so.

Normally to get access to an EGLContext from a QWindow you do so via
QOpenGLContext, but in setups without OpenGL but with EGL and OpenVG
this doesn't make sense (there would be no QOpenGLContext). So the
intended way is to use a QWindow to get an EGLSurface, then create
an EGLContext directly (without going through QPA).
