Jonas Ådahl 5e67e35ec5 compositor: Setup and use ownership chains
As with the backend commit, this means all objects can reach the
MetaContext by walking up the chain, thus can e.g. get the backend from
the context, instead of the global singleton.

This also is a squashed commit containing:

compositor: Get backend via the context

The MetaCompositor instance is owned by MetaDisplay, which is owned by
MetaContext. Get the backend via that chain of ownership.

dnd: Don't get backend from singleton

window-actor: Don't get backend from singleton

dnd: Don't get Wayland compositor via singleton

background: Don't get the monitor manager from the singleton

plugins: Don't get backend from singleton

This applies to MetaPlugin, it's manager class, and the default plugin.

feedback-actor: Pass a compositor pointer when constructing

This allows getting to the display.

later: Keep a pointer to the manager object

This allows using the non-singleton API in idle callbacks.
