## Description As the name suggests, `DML.Internal` contains internal implementation details of RQL's DML. However, a lot of unrelated parts of the codebase still use some of the code it contains. This PR fixes this, and removes all imports of `RQL.DML.Internal` from outside of `RQL.DML`. Most of the time, this involves moving a function out of `DML.Internal` to an underlying module (see `getRolePermInfo`) or moving a function _back_ into it (see `checkRetCols`). This PR also clarifies a bit the situation with `withTyAnn` and `withTypeAnn` by renaming the former into `withScalarTypeAnn` and moving them together. Worth noting: there might be a bug lurking in that function, as it doesn't seem to use the proper type annotations for some extension types!
