Add experimental flag for skipping synthesized symbols (#28)
Adds support for the generation of DocC archives without synthesized symbols by passing a new, experimental, plugin flag `--experimental-skip-synthesized-symbols`. Enabling this flag does not transform or post-process any of the passed arguments but overrides the default value of `symbolGraphOptions.includeSynthesized` that is provided to SwiftPM to false.
