Purpose

This PR implements visual improvements at node ports to indicate if a Function Node is in an active/inactive state.
A new rectangle was added in the output port to represent the active/inactive state.
Considering that Function State is represented by the boolean IsPartiallyApplied, here are how some states are working in the implementation of this PR.

State 1 - Function state but not passing a function (Output port is not connected to another node)

State 2 - Function passing (Output port is connected to another node and passing a function)

State 3 - All input ports are connected, so are not considered at function state anymore (Standard connected input colors)

State 4 - The input ports have default values, so it's not considered at function state (Standard connected input colors)
