TriggerMenuMT: Ensure that stream tag type is one of the allowed values
Make it impossible to define a stream tag with an invalid type.
It happened before - a type "delayed" was used, later fixed in !43981 (merged).
With this MR it will lead to AssertionError during menu generation:
AssertionError: streamType 'delayed' is not one of the allowed types: ['physics', 'calibration', 'reserved', 'debug', 'unknown', 'express', 'monitoring']
