thermal: core: Move some trip processing to thermal_trip_crossed()

Notice that some processing related to trip point crossing carried out
in handle_thermal_trip() and thermal_zone_set_trip_temp() may as well
be done in thermal_trip_crossed(), which allows code duplication to be
reduced, so change the code accordingly.

No intentional functional impact.
