Enable App OSS Tests (Desktop)

Moves most tests from app/src and app/rest/src to tests/ subfolders, and adds/updates CMakeLists.txt files to build the tests.

Note that several tests in each are disabled initially due to nontrivial google3 dependencies that need to be removed.  Bugs have been entered for tracking these: (b/138673663 for app/rest, b/138674328 for app).
