When creating a new config because of a monitor being (un)plugged or
because of super+p being pressed, honor the orientation reported by
the accelerometer for the internal panel.

Before this commit we would always configure the internal panel with
a normal / upright transform when e.g. an external monitor gets plugged
in even if another transform was in use before plugging in the external
monitor. This is inconsistent and causes problems for several use-cases.
This commit fixes this by querying the accelerometer when creating a new
config for an internal panel.
