This breaks weston_output_mode_switch() into 3 functions:
weston_output_mode_set_native()
weston_output_mode_switch_to_temporary()
weston_output_mode_switch_to_native()
Differences from previous behaviour:
SET_NATIVE didn't set current_scale (now it does)
SET_TEMPORARY could set mode and scale independently - now it can't.

Calling weston_output_mode_switch() with WESTON_MODE_SWITCH_RESTORE_NATIVE
will result in the mode being set "back" to the passed in mode - so the
passed mode should be the native mode.
Additionally, weston_output_mode_switch() should be called when
output->original_mode is non-NULL (which indicates we had a temporary
mode set). The comparison to current_mode results in a lot of
log chatter.
