Support windows with sRGB-capable default framebuffers in QSurfaceFormat
Backend implementation is done for GLX for now. WGL and EGL may follow
later on.
[ChangeLog][QtGui] Added support for requesting OpenGL windows with
sRGB-capable default framebuffers. While this is implicit on some
platforms, QSurfaceFormat now has the necessary flags to request
such windows in a cross-platform manner.
Task-number: QTBUG-50987
