drivers: sensor: mc3419: Change the TRIGGER config to a typical

Because MC3419's TRIGGER's Kconfig was different from the typical
configuration, the `build_all` test settings were not correctly
applied.

The Kconfig configuration has been revised to be set in conjunction
with MC3419_TRIGGER_OWN_THREAD, even if MC3419_TRIGGER is not
explicitly specified.
