Refactor: Create node_state context (part I)

[hhubert6]

I will add TreeNode struct to TermParser for better typing in components attributes and tests for TermParser in the next PR as this one is already pretty long.

Overall it looks fine but I'd like to clarify what's the reason for moving wrapper for live_render to NodeState.Web module

Since these are contexts and live_render is function used by other context it is a way of accessing this context (Simillar to how Phoenix contexts work on backend side where you expose functions to manage resources of one context). It basically is a nice way to expose functions to render elements form other context
