Add basic subscription test with dummy push server

This adds:

1. A dummy Python websocket server as a push service, which then opens a new HTTP server as a push endpoint for each subscription.

• This is done because we do not allow networking with external servers for WPT.

1. A encryption helper library that follows multiple web push RFCs.

• This is done because:
  1. Existing https://github.com/web-push-libs/web-push and https://github.com/web-push-libs/encrypted-content-encoding/ includes multiple codes that WPT don't need (e.g. multiple rs and legacy protocol support) and hard to read along with the specs.
  2. We want to generate intentionally ill-encrypted data for testing, which is harder with a third party dependency

Known caveats:

• The dummy server works but contradicts to the point for encryption; the dummy doesn't validate VAPID and implementing that part will make way more complexity with no actual extra test coverage.
  • We might instead want to somehow allow connection to the push server than adding a dummy server.
• Other servers don't send CORS headers which this test depends on
