feat: allowing x-jsf-logic to affect field attributes

[antoniocapelo]

Objective

This PR aims to allow x-jsf-logic schema to affect properties of fields.

Approach

After a brainy convo with @lukad we decided on a new approach to this:

• whenever we're about to interpret a schema (either on start or on change), if this schema has computed values defined, we make a copy of it, where all the computed attributes are correctly replaced by their computed values, and use that instead.
• this makes field manipulatio via x-jsf-logic way easier and it also removes the need for the validateJsonLogicComputedValues validation — since the schema has now the correct values in place, it can operate as with any other schema (hence some code being removed!)

Note for reviewers

You'll see more than a 1000 lines being added but this is because I ported all json-logic tests (and their fixtures) from v0 codebase. Please skip reviewing them as they're a copy-paste from v0 (except the part where I removed some of the tests as they were testing unused features that we dropped for v1)

Some examples that should work

Hey @antoniocapelo - left a few comments!

Took me some time but couldn't see anything major! Good stuff!

[dragidavid]

Seems good to me! We'll find out soon enough if I missed anything here 😅
