lessthanthree c7e7cb494f [MANUAL MIRROR] Lazarus Injected mobs don't fight each other (#19072)
* Dominate & Lazarus Inject basic mobs. Lazarus Injected mobs don't fight each other. (#72440)

Fixes #72404
The Lazarus Injector doesn't currently work on basic mobs, but should.

Problem:
The EMPed state of the Lazarus Injector is intended to make a revived
mob hostile to everyone except you, including other mobs you have
revived wtih an EMPed Lazarus Injector.
This is trivial to achieve for Simple Mobs which essentially all share
the same AI, but I could not think of a single workable solution for
Basic Mobs which don't, or at least any which didn't come with a tedious
requirement to closely consider this niche item when programming any
additional AI.

Solution:
Change the default behaviour of the Lazarus Injector so this is not a
problem.
If all it does it make the mob loyal to you _and_ friendly to other mobs
which are loyal to you, then it's pretty easy because we can just use
the existing faction flags.

This is unambiguously a buff to using the item for nefarious purposes as
now if you revive four ice drakes and fulton them onto the station they
won't kill each other until only one is left, but is the only workable
solution I could really think of.
A lot of the very dangerous mining fauna can't be dragged so
transporting your army to the station still poses a question.

The alternate solution was just to replace the AI controller of any
emp-revived basic mob with a "zombie" AI controller, but this has the
problem that
A- It would now make things like cows and dogs into hostile creatures
when they previously weren't.
B- It loses any interesting behaviour the mob previously had and for
cases like Bileworms doesn't even make any sense (they'd try to walk and
just get stuck in place).
This ultimately leads to needing to make bespoke versions for various
mobs, which doesn't seem desirable from a maintainability standpoint.

As a side note it's still not a great idea to revive Bileworms _anyway_
as, their ability to move is tied to their ability to attack so once
they don't have a target they will just kind of sit there and if they
_do_ get a target their attempts to help you fight are difficult to
distinguish from attempts to kill you... but at least being able to
revive them makes it easier to make one sapient if you really want to
trap a player's mind inside a body which is incapable of leaving
lavaland.

Additional edit:
At Fikou's suggestion I've also added a sentience comparison proc to
`mob/living` and removed some code duplication which dealt with this
problem in the sentience/mind transfer potions, as well as added it to
the Dominate spell.

This device is meant to revive mobs and it shouldn't be required for
players to memorise an arbitrary list of which mobs it does and doesn't
work on.
Especially as the goal is eventually that all simple mobs should be
basic mobs.
This way of working is more intuitive, even if it is also stronger. I
was surprised when I used EMPed injectors and my "new minions" just
killed each other.

🆑
fix: You can now revive 'basic mobs' with a Lazarus Injector, such as
dogs, cows, axolotls, or carp.
fix: The same category of mobs can also now be effected by the Runic
Golem Dominate spell.
fix: Basic Mobs will switch target if they can no longer attack their
current target; meaning that if you become a Bileworm's friend it will
stop attacking you.
balance: Mobs injected with the Lazarus Injector while it is EMPed will
no longer attack other mobs revived by EMPed Lazarus Injectors.
