Update REST API to be in sync with PHP API.

Currently REST API only exposes Criteria:
https://github.com/ezsystems/ezpublish-kernel/blob/master/doc/specifications/rest/REST-API-V2.rst#views

However this was changed in PHP API back in early 5.x days:
https://github.com/ezsystems/ezpublish-kernel/commit/6e540c579dbe5e556cdfc42e121d10a5817d694e

And cleaned up in 6.0:
https://github.com/ezsystems/ezpublish-kernel/commit/e2c171f31eabc93d26eccfc0a8a480ebf6393472

Sum: Deprecate Criteria and introduce Query and Filter.
