[dash-api]: Add dash-api and related protobuf library (sonic-net#14515)

Why I did it
For the DASH scenario, the APP_DB will be optimized by protobuf message for less memory consumption.

How I did it
Download the Debian package of protobuf 3.21.12 and create a corresponding rule for building it.
Add a submodule of sonic-dash-api and generated its Debian package which includes C++ library and Python library

How to verify it
Check artifacts of Azp that the protobuf-related and dash-api deb packages should be generated.
