Add "looks_like" to all furniture and terrain

[XygenSS]

Adds "looks_like" line to all terrain and furniture to help out tileset devs.

Summary

SUMMARY: Infrastructure Adds looks_like to all terrain and furniture entries

Purpose of change

Contributes to #34230.

Describe the solution

looks_like value have been added to all terrain and furniture JSON entries. One file named "looks_like hierarchy" have been added to /doc, it can be deleted when 34230 is fully resolved. Currently, all tiles eventually regress into t_rock and t_rock_floor which looks_like eachother. This can be easily changed if whitelist of some sort is added by editing a few major tiles (like t_floor and t_wall).

Describe alternatives you've considered

Not having stupid entries (e.g. an egg sack looks like a pile of rubble, which looks like rock floor) could've made more sense, but having everything consolidate into a few important tiles probably makes fixing stuff a bit easier (I think).

Testing

Not sure how to do it myself, but making a tileset with only t_rock and t_rock_floor to see if everything works perfectly could make sense.

Additional context

I got about halfway through. I will try to do more later. For the remaining half though, please try not to change an existing looks_like unless you've got a solid rationale, there are a lot here where you're removing what was a pretty good tag in favour of something that doesn't get the point across as effectively.
