python3-protobuf: Upgrade 3.11.3 -> 3.12.2

Upgrade to relase 3.12.2. Depends on the upgrade of protobuf
to 3.12.3 in meta-oe. The new release for Python brings:

- [experimental] Added proto3 presence support.
- [experimental] fast import protobuf module, only works with cpp
  generated code linked in.
- Truncate 'float' fields to 4 bytes of precision in setters for
  pure-Python implementation.
- Fixed a memory leak in C++ bindings.
- Added a deprecation warning when code tries to create Descriptor
  objects directly.
- Fix unintended comparison between bytes and string in
  descriptor.py.
- Avoid printing excess digits for float fields in TextFormat.
- Remove Python 2.5 syntax compatibility from the proto compiler
  generated _pb2.py module code.
- Drop 3.3, 3.4 and use single version docker images for all python
  tests.
