Chris Lu 7bfc44432d fix Rust build with protoc versions lacking native proto3 optional (#10343)
pass --experimental_allow_proto3_optional to protoc in the Rust build

filer.proto now carries a proto3 optional field, which the protoc 3.12
shipped in ubuntu-22.04 apt rejects unless this flag is set. Newer
protoc versions still accept the flag, so it is safe everywhere.
