feat: Extensions to makeStrictStyles

[ling1726]

Updates strict styles API to support component level extensions by leveraging generics throughout all the types. Example of usage

const useStrictStyles = makeStrictStyles<typeof Button>({
  strict: {
    alignSelf: 'center',
    // 👇 `maxWidth` only exists when Button style extensions are used
    maxWidth: '100%',
  },
});

// 👇 This is equally valid usage for the `Button` component without enabling component styling extensions
const useStrictStyles = makeStrictStyles({
  strict: {
    alignSelf: 'center',
  },
});

<Button className={strictStyles.strict}>Button</Button>
