feat: add useValue controller

Related Issue: #12278

Summary

This PR introduces a useValue controller for handling direct value changes and managing input and change event emitting behavior for form components that implement a value property.

useValue exposes the following API:

• inputValue({ inputEventEmitter: EventEmitter, value: string }) method that takes the component's custom input EventEmitter instance and the value to input. This will trigger the component's input event and should be called in response to direct user input, via keyboard and mouse events. useValue handles setting the component's value property and emitting the input event.
• commitCurrentValue({ changeEventEmitter: EventEmitter }) method that takes the component's custom change EventEmitter instance and handles committing the component's currently set value. This method should be called when the Enter key is pressed while the component has focus and when the component loses focus (blurred). useValue will emit the component's change event only if the component's current value differs from useValue's internally-managed lastCommittedValue.
• commitValue({ changeEventEmitter: EventEmitter, value: string }) method that takes the component's custom change EventEmitter instance and the value to commit. useValue will emit the component's change event only if the supplied value differs from useValue's internally-managed lastCommittedValue. This method should be called on Enter keypress or blur and only when there is a need to pass a custom value that is not already set on the component, such as a reset or clear event where the new value is being set to "" or needs to be restored to a different value, or if the value needs to be validated prior to committing.
• useValue handles default event prevention for the component's input and change events, restoring the component's value to its internally-tracked previousValue property.
• useValue also knows not to emit any input or change events when the value is directly modified on a component instance as long as only the above methods are utilized to modify the value in direct response to user input.
