Add flag to disable generation of withX, addX, clearX methods

[dgrnbrg]

Hello, it looks like very large protobuf definitions can cause scalac to generate classes that exceed the JVM's class bytecode limit. I've inlined an example protobuf below. It's possible that this is due to with with/add/clear methods being generated; perhaps removing them would allow this file to build?

This is on Scala 2.12.5.

Here's the error message:

error: Could not write class com/foo/bar/bar/MyProto because it exceeds JVM code size limits. Class file too large!

I'm closing this because it may just be correlated to pre-scala 2.12.8, and this feature is really to enable builds, not because I don't want those nice functions.
