Don't create the Kapt generate stubs output dir in lazy initializer

Browse Source 
Creating a directory in the property getter interferes with Gradle cache
 outputs snapshotting, resulting in build cache being disabled for the
 task with the following info message:

 Caching disabled for task ':app:kaptGenerateStubsKotlin': Gradle does
 not know how file 'build/tmp/kapt3/incrementalData/main' was created
 (output property 'destinationDir'). Task output caching requires exclusive
 access to output paths to guarantee correctness.

 As Gradle automatically creates any @OutputDirectory, we don't need
 to create it at the task initialization phase.
