Option to verify timestamp of programmatic submission

Problem/Motivation

Drupal module webform_rest → provides an API to do webform submissions.
These are counted as "progammed" submission, and honeypot does skip the validation for time restrictions in that case since 2677126 → .

It would be nice if there was a way to tell honeypot that programmed submissions shall have the time restrictions validated.

Proposed resolution

HoneypotService could have a method "setValidateProgrammedForms" which would allow enabling/disabling time restriction checks for forms whose $form_state->isProgrammed() returns true. That way webform_rest could enable it before creating the webform submission, and disable it afterwards.

Maybe there is a better way that does not involve using a "global" scoped variable inside the honeypot service, but I don't know the code good enough.
