Ports the new parts of https://github.com/Baystation12/Baystation12/pull/15298 back to Polaris

* Changes navbeacons to no longer use radios (Doing so was slower and didn't really help anything) Note: var/freq remains for mapping compatibility until all maps are updated.
  * Fixes navbeacons to actually hide under flooring if you put plating over them.
  * Changed how navbeacons are mapped in.  Don't use the picky "code_txt" variable, instead use appropriate subtype.
  * Made useful reusable subtypes so you don't have to code in a type for every. single. one.
* Updated mulebot to use new navbeacon codes.
* Re-activate patrolling!  With the new navbeacons, bots with will_patrol can follow the patrol navbeacons.
  * Note: various "should_patrol" variables on each bot type unified under /mob/living/bot/var/will_patrol
* Securitrons (beepsky) got an overhaul to the new patrol routing.
  * Note: BayStation replaced the snowflake handcuffs code with acutal handcuffs.  Polaris handcuffs requiere a grab to work, so are more complicated.  Kept our existing attack code.
  * Behavior procs reorganized to use better movement detection and just be more flexible.
* Floorbot fixes & removal of bridgemode
  * Floorbot will now remove & replace broken floor tiles.
  * Floorbot will no longer decide its okay to pave over all of SPACE.
  * For the moment patching hull breaches is disabled, it is too laggy.
* Sundry bugfixes to all bots
  * Use forceMove() instead of setting loc
  * Use "\The [X]" message strings.
  * Pass target to do_after() when doing something to a target.
* Fixed events that were supposed to emag bots to now do so again.
