This commit moves the compiler compliance tests into compiler-cli,
and uses ngtsc to run them instead of the custom compilation
pipeline used before. Testing against ngtsc allows for validation
of the real compiler output.
This commit also fixes a few small issues that prevented the tests
from passing.
