Add DisplayViewport native tests

The strategy for finding DisplayViewport has changed in ag/4723479.
Add native tests for the new lookup logic here.

The matching is done by uniqueId if it is specified, and by type only if it is not.

Some additional refactors:
- Return std::optional from getDisplayViewport
- Make internal viewport optional. Expect normal operation if internal
viewport is not present at all.
