protobuf: Upgrade 3.11.4 -> 3.12.3

Upgrade to release 3.12.3. Update the path to the git repository
in GitHub. Update the patch for examples/Makefile.

The new release brings:

- [experimental] Singular, non-message typed fields in proto3 now
  support presence tracking. This is enabled by adding the
  "optional" field label and passing the
  --experimental_allow_proto3_optional flag to protoc.
- Allow duplicate symbol names when multiple descriptor sets are
  passed on the command-line, to match the behavior when multiple
  .proto files are passed.
- Deterministic protoc --descriptor_set_out
- Bug fixes for the supported programming languages
