Add planters, allow plants to be grown on furniture

[anothersimulacrum]

Summary

SUMMARY: Content "Adds planters"

Purpose of change

Resolves #29972
The game was missing options to grow plants anywhere but on t_dirt

Describe the solution

Add two new fields plant_transform and plant_base to furniture
Add 5 new flags - GROWTH_ SEED, SEEDLING, MATURE, HARVEST, and PLANTABLE
Adjust iexamine::plant_seed, iexamine::aggie_plant, map::grow_plant, activity_handlers::harvest_plot_do_turn, activity_handlers::plant_plot_do_turn, iexamine::harvest_plant, and mattack::eat_crop to use the new fields and flags to do their functions
Add planter terrains

Amount of soil used in planter recipe based on calculations from this with dimensions of 3'x3'x18"

Describe alternatives you've considered

Leaving planting as only allowing terrain ( a simpler solution ), but that doesn't really address the issue

Additional context

I don't know C++, so I probably broke style rules and did things in a less than optimal manner
Thanks @curstwist for the planter furniture

I think the fact that you're willing to try and learn says a lot, and starting with a Draft PR was a smarter choice.

Make sure to add the definitions for these new JSON flags in /doc/JSON_FLAGS.md.

Did not review code --- will leave that to more experienced people.

As far as I can tell, everything works now, so I think this is ready for review.
