[cogl] Remove cogl_context_set_default API

[Robert Bragg <rbragg src gnome org>]

commit 09e7174b1dd2d46f8e94b6eecdff947e12716d59
Author: Robert Bragg <robert linux intel com>

    Remove cogl_context_set_default API
    
    For cogl 2.0 we don't want to have a default context. In the meantime
    we can simply assume that calling cogl_context_new() implicitly
    sets that context as the default context before returning.
