tp: move metrics descriptor generation to build time
This is necessary because generating the descriptor at check-in time was
leading to conflicts in G3 where the third_party/perfetto prefix is
present for extensions defined in Google3 but not the builtin
descriptors.
This CL ensures that wherever we build, we get a consistent generation
of the builtin metric descriptor.
