drm-tests/plane_test: add support for external displays
This CL adds a flag --external (-e, like gamma_test) so especify
that all commands should be directed to the external DRM connector
and not the internal, which is used by default.
BUG=b:183760490
TEST=/usr/bin/plane_test --external --format XR30 on volteer with
a DP connected external screen does what it's supposed to do on
the external screen. No "--external" uses the panel.
