Use kapt stubs for kotlin header jar for javac

Browse Source 
When compling kotlin code with annotation processors we are generating
java stubs for the kotlin sources using kapt, and parsing them in
turbine when running the annotation processors.  Passing --output
to turbine will also compile the stubs into a header jar that can
be used as a dependency to javac, allowing the javac and kotlinc
rules to run in parallel.  The turbine-apt header jar can't be used
as the header jar for downstream modules as it doesn't contain the
kotlin metadata needed by kotlinc rules, so the kotlinc gen-jvm-abi
plugin output is still used for the module's final header jar.
