Export all public types directly from workbox-window

[StephanBijzitter]

As a follow-up on #2255

Library Affected:
workbox-window.

Browser & Platform:
TypeScript

Issue or Feature Request Description:
While a lot of the types can currently be imported, they do use the source filepaths, which could break at any point as SemVer does not (and should not) handle things like that.

So this, while currently valid, is prone to break:

import {WorkboxMessageEvent} from 'workbox-window/src/utils/WorkboxEvent';

The pull request above allows us to import types for workbox-core directly, but sadly this is not the case for workbox-window.

Sounds reasonable!

Feel free to file a PR to accomplish this if you're comfortable doing so—otherwise, someone from the core team will pick it up.

Hi I would like to contribute to this issue

[jeffposnick]

Thanks! I think the PR at #2919 already addresses it, though.
