fix(compiler): update to metadata version 3 (#13464)

Browse Source 
This change retracts support for metadata version 2.

The collector used to produce version 2 metadata was incomplete
and can cause the AOT compiler to fail to resolve symbols or
produce other spurious errors.

All libraries compiled and published with 2.3.0 ngc will need
to be recompiled and updated with this change.
