[Blockly] Add access to semantic actions

[rkoshak]

The problem

Outside of the "inline script" block there is no way to get the parent location Item nor the parent equipment Item nor execvute any of the other Semantic Actions: https://www.openhab.org/docs/configuration/actions.html#semantics

Your suggestion

In openhab-js, these have all been made available on the Item: https://openhab.github.io/openhab-js/items.ItemSemantics.html.

items.MyItem.semantics.isEquipment;
items.MyItem.location

etc.

I don't know though if it make sense to just add these as properties to the "get [name] from item" block or if it makes sense to add a new block. Since they are all exposed as properties the former makes sense to me but the list of properties for that block might be getting a little bit too long an ungangly and it makes sense to keep them in separate blocks.
