Description
ChimeraX on Mac is giving a startup warning
Attribute Qt::AA_ShareOpenGLContexts must be set before QCoreApplication is created.
This is a Qt bug, the warning comes from QWebEngine initialization as described in this Qt 5.12 bug report
We also use a shared context when we go into sequential stereo so we should set this attribute and test that ChimeraX stereo is still working.

This warning will be fixed in a future version of Qt.
Our code was not setting this attribute, but it should set it so that stereo and mono opengl contexts share vertex buffers. I added code to set Qt.AA_ShareOpenGLContexts.
