An abstract base class (Device::Context) is used to avoid adding dependencies to Device, with ContextEGL derived from it. This also
leaves open the possibility of supporting other native GL contexts
in the future (e.g., glX). One temporary EGLContext is created by opengl::Backend during Adapter discovery, then one is created for and
owned by each Device.
Contexts for the desktop GL backend are also managed via EGL, which
works for most modern drivers. This also means that GLFW is now
always used in GLFW_NO_API mode.
Since contexts are now per-device, all of the default GL state
setting and debug output setup was moved from Adapter to Device.
