Handle moving a UI-side composited window between displays with different
properties

Reviewed by Tim Horton
On macOS windows can be moved between displays with different colorspaces, so
with
UI-side compositing we need to ensure that we update layer backing stores with
the
new colorspace.
To fix this, add the colorspace to RemoteLayerBackingStore::Parameters, and
initialize
it in PlatformCALayerRemote::updateBackingStore() by getting the colorspace
from the
RemoteLayerTreeContext (on macOS). This allows the existing call to
`ensureBackingStore()`
to do the right thing when the colorspace changes.
We rely on the fact that moving between displays triggers repaints in all
layers already
to make sure that we hit PlatformCALayerRemote::updateBackingStore().
