* Implements timed_action_flags for do_after-like procs (#54409)
Originally I wanted to fix an issue where the `get_up()` `do_after()` would ignore the callback checks, because it was `uninterruptible`, so that made me refactor these procs to allow for higher granularity on checks and standardize behavior a bit more.
There's more work to be done for them, but one thing at a time.
* Removes the `uninterruptible` check in favor of the more granular `timed_action_flags`
* Cleans code on the `do_atom`, `do_after_mob`, `do_mob` and `do_after` procs to standardize them a little better.
* Implements timed_action_flags for do_after-like procs
* Update horror_form.dm
