cmd/go: propagate origin information for inexact module queries
Module queries for "@latest" and inexact constraints (like "@v1.3")
may consult information about tags and/or branches before finally
returning either a result or an error.
To correctly invalidate the origin information for the -reuse flag,
the reported Origin needs to reflect all of those inputs.
Fixes #61415.
