Adds a new SourceProvider type to generate grpcio code from protos.
Since it's so similar to protobuf, it's basically just a different type
of rust_protobuf.
Bug: 171504899
Test: Example module compiles.

* Upgrade to new protobuf-codegen; use its standard
default output without local change.
* Allow a sourceProvider to have multiple output files.
For a stem.proto file, output stem.rs and mod_stem.rs.
* New protobuf-codegen option gen_mod_rs always generates
output file named "mod.rs". To generate multiple .proto
files into the same output directory, we need to rename
mod.rs to mod_<stem>.rs.
* Instead of using the gen_mod_rs option and renaming mod.rs
to mod_<stem>.rs, we generate the same mod_<stem>.rs
directly with a simple printf command.

This adds a new SourceProvider module type to handle protobuf code
generation. See the new test for an example of how to call this.
