Semantic model configs - enable/disable + groups

[emmyoop]

resolves #7968
docs

Problem

Semantic models cannot be enabled/disabled and also cannot belong to groups.

Solution

Enable configs to allow semantic models to be disabled and be in groups.
When a semantic model is disabled but the defined metric for the measure is not, it throws a ParsingError.

Thank you for doing this work! It's looking great 🙂 One thing that caught my attention is that we're handling disabled semantic models during resolution differently than we handle resolution of all other nodes. It confused me for awhile, and then I recognized that it was necessary due to our indirect referencing from the measure being the intermediary for the lookup (making the DisabledLookup not fit this use case).

It feels weird to me. Seems like we might need a refactoring here sometime, but I think that's out of scope for this.
