fix(runtime): autocapitalize property is a string (#3692)

In #2509, we changed these types to `any` as suggested by Manu. This was done to fix ionic-team/ionic-framework#21464.

Upon further investigation we found that this fix was not correct. The Framework issue had nothing to do with the types on `HTMLStencilElement` and instead were related to the types on `HTMLElement`.

It's worth noting we didn't got the route of specifying the allowed strings further to `'off' | 'on' | 'none' | 'sentences' | 'words' | 'characters'` to align with `lib.dom.d.ts` that's shipped with TypeScript, which just types this property as `string` (on `HTMLElement`). Had we done that, we could/would have run into issues where `string` isn't assignable to `'off' | 'on' | 'none' | 'sentences' | 'words' | 'characters'`, as the former is wider than that latter.
