Feat: support typed select values (Proof of Concept)

Description

Whenever we code select we pass in Enum Strings that match our API 1:1. Since Cloudscape Select Components Option & OptionDefinition has value typed as a string.

We end up needing to type cast the output (when onChange event occurs)

It would be nice if cloudscape components supported a generic that let you scope down further than just string (specifically string enums).

I included an example using the existing tests

export declare const SelectValues: {
  readonly FIRST: '1';
  readonly SECOND: '2';
  readonly THIRD: '3';
  readonly FORTH: 'Option 4, test"2';
};

export type EnumStringType = (typeof SelectValues)[keyof typeof SelectValues];

The way this has been implemented, it defaults to string if you don't pass a type.

Behaviour will be unchanged if you don't pass a type, and if you do pass a type that type still needs to extend a string.

How has this been tested?

Easiest way to test it, is to pull this and play around with it.

I'm making this PR, so I can play around and test this a bit more extensively.
