[mutter] tests: Introduce MetaContextTest

[Marge Bot <marge-bot src gnome org>]

commit e17bf88d5eccbd2651548d60eb7b20155223336c
Author: Jonas Ådahl <jadahl gmail com>

    tests: Introduce MetaContextTest
    
    This introduces a MetaContext implementation aimed to be used for test
    cases, with as little boiler plate as possible needed in the test.
    
    It currently doesn't do anything, just fills out the GObject boiler
    plate and sets a name.
    
    Build it into every core test, for compilation, even though it isn't
    used anywhere yet.
