iOS: Add support for offscreen GL surfaces without using hidden windows
There's no need to create a hidden window to get a surface on iOS, as
the platform supports FBOs. Note that defaultFramebufferObject() returns
0 in the case of offscreen surfaces, which is technically not a valid
FBO on iOS due to the indirect rendering, but binding and rendering
to the zero-FBO seems to be no-ops, so clients may safely call eg
glBindFramebuffer(GL_FRAMEBUFFER, ctx->defaultFramebufferObject())
to restore the default FBO after drawing to its own FBO.
