After this change //daml-lf/tests:test-scenario-stable-many-fields
does not seem to stack overflow anymore.
This is a workaround until we make the type checker stack safe, See #13410.

CHANGELOG_END
* Update protobuf to include viewtype and implementation view
* Stub interface viewtype and implements view in updated AST
* Set views on Java builders in DecodeV1Spec

not currently linked to syntax or engine changes, all stubbed out in
LFConversion.

Namely, it does not point to a conversion function, and the actual value it points to is irrelevant.
Only its presence is used to determine whether a template implements an interface or not.
Consequently, it now points to the unit value instead of the identity function.

Also factor out check into private function
