Chore/resolve map and provider

Description

This PR refactors local map and provider resolution. It removes overly complicated resolveValue function and it introduces separate functions for local map and provider resolution. It also improves validation of loaded files.

This should NOT be braking change. But in cases of poorly configured SDK this change may lead to throwing valid errors (we are checking that eg. profile id in map ast matches profile id in super.json)

This PR is ready we just need to decide if this is shippable under minor change.
