Add emit/test (pytorch#3933)

Summary:
Note that two tests are passing on internal but not OSS. Skip for now.

Change the test backend name from BackendWithCompilerDemo to BackendWithCompilerExample because BackendWithCompilerDemo is packaged by exir/backend/test/test_backends.py and could cause confusion in pytest.
