Make staticcheck do a recursive check (#639)

* Don't prepend module name for in-namespace fields of a non-root-level GoStruct

For details see #637

Fixes #637

* Remove generated proto files

* re-add proto files

* Update ValidatedGoStruct and deprecate GoStruct

* Remove != nil check since method is nil tolerant

* Fully deprecate GoStruct

* Make staticcheck do a recursive check
