[Feature]: Support generate pyi for python binding #100
Description
Requirement
In protobuf 3.20.0, we can use protoc to generate pyi for python's type hint. This has been pulled into a released gRPC version(>= 1.48.2, as metioned here: grpc/grpc#29650 (comment))
Note that the current version of grpc is 1.35.0, so in the next upgrade, if the version is met, hopefully the relevant builds will be added.
Problem
pyi will provide python users with a great programming experience and enable type-checking tools.
