Add SwiftFormat and SwiftLint disable commands to generated code (#350)

This mirrors the behavior that exists in swift-protobuf. One can see
examples of this and the pattern it directly mirrors in any `.pb.swift`
file.

The output from updated generator is demonstrated in the regenerated
files within the repository itself.

Fixes #349
