* Remove ELEMENT_DETACH on everything that doesn't need it, rename to ELEMENT_DETACH_ON_HOST_DESTROY + a PSA (about 0.2s init time savings) (#70972)
ELEMENT_DETACH is **not** a requirement to having `Detach` called.
Detach is always called when the element itself is destroyed.
ELEMENT_DETACH is a flag that when set, makes sure Detach is called when
the atom destroys.
Sometimes you want this, for instance:
```dm
/datum/element/point_of_interest/Detach(datum/target)
SSpoints_of_interest.on_poi_element_removed(target)
return ..()
```
This Detach cleans up a reference that would have hung if target was
destroyed without this being called.
However, most uses of Detach are cleaning up signals. Signals are
automatically cleaned up when something is destroyed. You do not need
ELEMENT_DETACH in this case, and it slows down init. This also includes
somewhat more complex stuff, like removing overlays on the source
object. It's getting deleted anyway, you don't care!
I have removed all uses of ELEMENT_DETACH that seemed superfluous. I
have also renamed it to `ELEMENT_DETACH_ON_HOST_DESTROY` to make its
purpose more clear, as me and a lot of other maintainers misunderstood
what it did,
---
An update to this, ELEMENT_DETACH *is* needed for anything that can
register to a turf, as turfs do not clear their signals on destroy.

* Spiders/carp will now pull/move water/welding fuel tanks/canisters slower and won't be able to attack stationary atmospherics equipment (#61616)
Adds 2 new elements, one for slowing down pulling of dangerous objects (dispenser tanks and canisters), and one for preventing hostile attacking of elements in a typecache.
Also updates the obj_flags bitfield 'cause I thought I was gonna use that, but I didn't.
Adds these elements to spiders and space carp (from space dragon)
