Adds grid forge rigs, chemistry sets, and chemlabs

Summary

SUMMARY: Content "Allow wiring up electric chemistry sets, vehicle forge rigs, and vehicle chemlabs to grids"

Purpose of change

This adds a few more grid-placeable utilities, in particular making some over vehicle parts reusable for grid purposes in case you're stuck with those.

Dependent upon #2172 since this includes fun stuff like chemistry sets (which are multi-function), and also consistent with #2155.

Describe the solution

1. Added grid forge rigs. Copies from regular forge to be a bit less chonky.
2. Added grid chemistry sets and chemistry rigs, the latter copying from the former.
3. Defined fake item for grid chemistry sets, uses the qualities of a full chemistry set while substituting for basic chemistry sets (since grid chemistry set furniture already includes fake oven which substitutes a hotplate, and the upgraded chemistry set also subs for a hotplate).
4. Defined construction entries and construction groups for new furniture.
5. Misc: Also converted grid welding rigs to use copy-from.

Describe alternatives you've considered

Procrastinating.

Testing

1. Loaded the forge rig change in a compiled build, did this before implementing the chemistry set stuff since it won't be happy with having crafting_pseudo_item as an array until Kheir's PR is merged.
2. Debugged in a grid forge rig, confirmed that copy-from correctly carries over crafting_pseudo_item.
3. Debugged in a grid welding rig, confirmed that copy-from correctly carries over examine_action.
4. Checked affected files for syntax and lint errors after implementing the stuff that uses crafting_pseudo_item arrays.

Additional context

Note to self: The existence of use_furn_fake_item means I can borrow a page from Cataclysm++ and give forge items a repair use action without vehicle forges being broken, something I've wanted to do for years (in fact technically it was added to can forges in Cata++ specifically because furniture forges didn't play nice with having use actions).

This will most likely need updating to fix merge conflicts once Kheir's PR is merged since it also touches grid welder rigs.

I'm pretty sure I'm getting it from this PR:

electric_grid_test.cpp:441: FAILED:
  REQUIRE( sm->get_furn( pos_in_sm.raw() ).id() == f_floor_lamp_on )
with expansion:
  string_id( "f_null" )
  ==
  string_id( "f_floor_lamp_on" )
with messages:
  pos_abs := (550,7,0)
  pos_abs_sm := (45,0,0)

#1204 is the one that messes with the grid code, this one just adds more grid furniture with psuedo tools.
