Makes advanced factories possible -- Bunch of changes to mech component and the assembler (#5121)

## About The Pull Request

- Adds examine text telling you that you that using a multitool on mech
components is how you interact with them
- Makes it so right-clicking with a multitool on a component
automatically sets your multitool buffer to the link
- Makes interaction components capable of only choosing a specific type
of item instead of all items on a tile (AKA, a filter)
- Makes assemblers actually have ALL the recipes in the crafting book by
taking it from `GLOB.crafting_recipes` (except restricted ones)
- Removes the 10x longer coffin crafting recipe that bloodsuckers added
for no reason

## Why It's Good For The Game

> Adds examine text telling you that you that using a multitool on mech
components is how you interact with them
- Somehow we didnt have that, was also needed for the next point
> Makes it so right-clicking with a multitool on a component
automatically sets your multitool buffer to the link
- Speeds up the repetiveness a bit
> Makes interaction components capable of only choosing a specific type
of item instead of all items on a tile (AKA, a filter)
- Ever wanted to make a conveyorbelt with items and only interact with
the items? Now is your chance to do so!
> Makes assemblers actually have ALL the recipes in the crafting book by
taking it from `GLOB.crafting_recipes` (except restricted ones)
- They didnt have the recipes from sheets of items, now they do, so a
lot more is possible combined with the interaction comp filter.
- ((This does mean cargo can make coffins 10 times faster now, since
that recipe is also taken into account. Can be slowed on request))
> Removes the 10x longer coffin crafting recipe that bloodsuckers added
for no reason
- Bug :3

## Changelog

:cl:
add: Interaction components can now have a filter that only interacts
with specific items.
qol: Mech components can now have themselfes quickly put into the
multitool buffer as a device to link if you right-click them.
balance: automatic assemblers can now make any* crafting recipe thats
made using sheets in your hand
fix: There is no longer a coffin recipe that takes 10 times as long to
craft in the crafting menu.
