Feat/grid improvement

[finger563]

Description

• Move code to place item into inventory into the base of the grid item, so that simply calling interact on it will do the same work
• Simplify the grid interaction code some, prep for future refactor / simplification
• Add actual classes for pickups instead of just using the bases for moss / bigmoss
• Add non-grid placed items into level for interaction
• Update grid item to have interaction box, which is set to either item size or the grid size (if it is in a grid) - implement the placed in grid event handler to update the size
• Update data table accordingly for new pickup items

Motivation and Context

Starts on the refactor for how we handle interaction and starts to allow growables / foragables / interactibles to existing in the world without being in a grid.

How has this been tested?

PIE and tested all grid systems work, as well as non-grid items.
