Investigate whether sending whole State object to a Tool automatically if State is in the tool's function signature would be beneficial.

A pro of this would be that it would be easier for developers creating tools from scratch to read/write from State without having to worry about using the inputs_from_state and outputs_to_state tool params which can at times be clunky.

However, this runs the risk of being able to do the same thing in too many different ways which could lead to user confusion about what's best-practice or the recommended route to use.

This idea has popped up a few times when talking with @deep-rloebbert, @sebastianh-deepset and @kacperlukawski as a way to make manipulating the Agent's State behavior easier when working directly with code.
