chore(bidi): implement permissions API (#35662)

Limitations due to current Bidi protocol:

- Cannot revert to the browser default permission (before override). So when the client calls clearPermissions
 we always set the permission to `prompt` which is not necessarily what the browser had before the override.
- `*` pattern is not supported. Most clients don't want to do fine grained permission control in their tests.
