Simplifies interaction input handling and refactors reload logic to be more performant

[aronand]

• Simplifies PlayerInteractionComponent by merging input checks for interact and interact2 to a single block
• Removes a RayCast3D.is_colliding() check and gets that information via RayCast3D.get_collider() (null if no collision)
• Rewrites the reload logic (removes nesting, removes the while loop, makes the for loop faster by removing the use of InvetoryPD.remove_item_from_stack())

Reload time after:

Good catch! I'll have a look during the weekend. Mainly focused on testing the pistol and didn't realize the mechanics are different for different wieldables.

Fix is in now. Tested both the flashlight and the laser rifle, which now seem to function as intended.
