Substations now explode when destroyed (#5729)

* Substation destructible component

Substations now explode and create a destroyed machine which can be deconstructed.

* construction graph test failed

Does not need a path from start to finish but adding anyway to fix tests

* railing to structures

* Fixed Review

Updated parent to fix most comments.
Updated node to camelcase

* Updated target node graph

Still recovering...

* Final fix of graph

I swear

* Altered destroyed machine spawns

Removed HV cable and reduced steel sheets.
