Subject: Fix for eglfs context sharing problem in qtwebengine widget

EGLFS backend does not use global sharing context. WebEngineWidgets was
failing to access textures created by WebEngineChromium and textures
were ending up as black rectangles.

This fix initialises window surface context with shared context and
fixes the bug.
