Feature: restructure RCS thruster casing and ponder added

[Flussen]

Summary

• Set complete RCS block states for brass, copper, and railway casing transitions.
• Rebuild the RCS Thruster Ponder to add casing states.
• The RCS thruster remained unchanged in its normal state, only the possibility of adding a casing block was added.
• When break the block or use Create wrench, it returns the used casing block and the thruster.

Looks good, though question -- why are you implementing casing through a block property instead of through separate blocks and the Create interface and registry, like how Create handles encasing?

[Flussen]

There's no specific reason, I wasn't familiar with how Create worked, but I'll definitely have to change it. I hope to fix it soon

I've worked out this idea, however, I don't see how the train casing can be connected to other train casing blocks due to its internal system. Nevertheless, the possibility exists and it could be useful

I do not think we want to give the light weight tag to the encased thrusters, since these casings do not have it themselves iirc.
