Introduce mostly empty MetaContext type

This type is intended to replace the scattered functions used to configure how the Mutter compositor is run. It currently doesn't do anything, and only has a human readable name, intended to be set to e.g. "GNOME Shell". It's an abstract type, and is intended to be used via either a future `MetaContextMain` for real display server use cases, and a `MetaContextTest` for test cases.
