feat: add proof-of-concept implementation for strict fully validating using draft-06 schema

[DannyvdSluijs]

⚠️ This is a draft PR as some blockers have been resolved breaking other things in order to get a proof of concept of the approach for supporting multiple drafts.

This PR will:

• Introduce the JsonSchema\Constraints\Drafts\Draft06 namespace
• A constraint per keyword
• Enable the draft6 in the test, locally I have 633 passing test, 312 failing tests and 157 ignored tests.
