It already does this for builtin validator calls, let it do the same for non-validator calls as well. This is a net reduction in code size, given that the adt package already has a bit of code to stringify a builtin func name. Moreover, a few dozen errors were missing this wrapping entirely, given that they failed in ways that internal/pkg did not cover. As a bonus, we also avoid stuttering in builtin validator calls, and we save about 0.4% of allocated objects in the Inventory module.
