[MIRROR] Improves the deployable component [MDB IGNORE] (#24627)

* Improves the deployable component (#79199)

## About The Pull Request

The deployable component had a few random things I noticed when I tried
actually using it that kinda sucked so I'm:

Making the examine message more generic, we did NOT need to make it that
complicated.
Letting anything with hands deploy stuff, because mobs other than humans
can hold things.
Giving the option to let something be deployed more than once.
Letting direction setting be optional.
Tweaking the check for if something can be placed somewhere to be a bit
better.
## Why It's Good For The Game

I want to use the deployable component for stuff but I made it awful.
## Changelog

code: the deployable component has been tweaked and improved with some
new options to it

  * If attaching this to something:
  * Set deploy_time to a number in seconds for the deploy delay
  * Set thing_to_be_deployed to an obj path for the thing that gets spawned
- * Lastly, set delete_on_use to TRUE or FALSE if you want the object you're deploying with to get deleted when used
+ * Multiple deployments and deployments work together to allow a thing to be placed down several times. If multiple deployments is false then don't worry about deployments
+ * Direction setting true means the object spawned will face the direction of the person who deployed it, false goes to the default direction
