Add Attribute Modifiers Display (#3728)

Browse source 
* Add Attribute Modifiers Display

Allows Bedrock players to view the Attribute modifiers display on the bottom of items.

* Fix handling for Knockback Resistance

For some reason, Knockback Resistance is multiplied by 10 in the display for addition, so this handles that oddball.

* Add null check for NBT

* Remove "contains" check

This is checked in the beginning of the addAttributes method so is not required here.

* Add curly brackets

Camotoy likes curly brackets I guess

* Use ModifierOperation enum instead of int for clarity
