Relocate shaded JSON API in annotation-processor

Browse Source 
Move the 'shade' copy of the JSON API to a separate src folder to make
it clearer that we don't own the code. Also polished some formatting
and suppressed a few warnings.

## Shaded JSON
This source was originally taken from `com.vaadin.external.google:android-json` which
provides a clean room re-implementation of the `org.json` APIs and does not include the
"Do not use for evil" clause.

* long 9223372036854775807.</a>
* <li>When the requested type is a String, other non-null values will be
