Batrachophreno 4ecb0bc21c Repath obj/machinery to obj/structure/machinery [MDB Ignore] (#22500) 
Repaths obj/machinery to obj/structure/machinery. **Note for
reviewers:** the only meaningful changed code exists within
**code/game/objects/structures.dm** and
**code/game/objects/structures/_machinery.dm**, largely concerning
damage procs. With the exception of moving airlock defines to their own
file, ALL OTHER CHANGES ARE STRICTLY PATH CHANGES.

Objects, _categorically_, are largely divided between those you can hold
in your hand/inventory and those you can't. Machinery objects are
already subtypes of Structures behaviorally, this PR just makes their
pathing reflect that, and allows for future work (tool actions, more
health/destruction functionality) to be developed without unnecessary
code duplication.

I have tested this PR by loading up the Horizon and dismantling various
machines and structures with tools, shooting guns of various types
throughout the ship, and detonating a bunch of explosions throughout the
ship.

/*
Every cycle, the pump uses the air in air_in to try and make air_out the perfect pressure.
node1, air1, network1 correspond to input
node2, air2, network2 correspond to output
Thus, the two variables affect pump operation are set in New():
air1.volume
This is the volume of gas available to the pump that may be transferred to the output
air2.volume
Higher quantities of this cause more air to be perfected later
but overall network volume is also increased as this increases...
