Adds table flipping! Take 2.0 (#90156)

## About The Pull Request
Revives the long dead #80348. Right click a table to flip it over,
Useful for makeshift cover or ragequitting. Their integrity is equal to
that of the table you flipped. Some tables aren't able to be flipped
(reinforced tables, roller tables, etc).

I refactored it to be less snowflakey. so hopefully this passes with
only minor changes

## Why It's Good For The Game
I felt like we're lacking in the makeshift defense items. This is a
quicky way to plop up a shitty barricade for you to guard with. and also
really cool for roleplaying and such. also, this categorically goes
hard:
