Object Examine Text Overhaul (#20923)

Extends and reworks how various extended information text (desc_info,
desc_build, desc_upgrades) are handled to make object interactions and
mechanics A.) much more clearly documented in-game and B.) much easier
to support from the back-end.

Almost certainly a candidate for test merge.

Assembly/Disassembly instructions are noticeably sporadic, largely due
to our current lack of a unified framework. That's a future thing I'd
like to attack so that it can be handled programmatically, but for now I
only targeted the biggest culprits as I came across them.
