Re-init renderer for all outputs on lost context

Browse source 
sway_root.outputs only include enabled outputs. We also need to re-init
the renderer for any disabled outputs, so use sway_root.all_outputs
instead.

Resolves the following heap-use-after-free accessing the render formats
when a disabled output is modeset after a GPU reset has occurred.
