Description of the feature request:

Module extensions should be able to fail on a particular module extension tag so that the emitted stack trace points to the location at which the particular tag was created by the user.

What underlying problem are you trying to solve with this feature?

When a user specifies an invalid module extension tag in their MODULE.bazel file (e.g. a version of a dependency that isn't valid) and the module extensions fails due to that, the stack trace starts with the module extension implementation function. There is no way to reference the particular tag that caused the failure, which makes it unnecessarily difficult for the user to fix the issue.
