Handle Parsing of Type Tree's passed as metadata

Yeah in particular we want to remove the special cases for Julia in the tbaa analysis.

I think there's two separate things here that need to be done

1. An interface for passing in TypeTree's at the calling boundary
2. An extension mechanism to Type Analysis to handle custom rules (e.g. jl_apply_generic)

[wsmoses]

Incidentally this is now (partially) handled by #93 .

We still need the special case for Julia TBAA info presently (unless we ahead-of-time add calls to enzyme_float, etc) as the custom rule is only for functions, not for custom TBAA info.
