This change expanded KAPT to support a new param
'fileAccessHistoryReportFile', which reports all the classes used during
annotation processing into a file, in the form of a list of URIs.
This is useful for build speed improvements described in https://engineering.fb.com/2017/11/09/android/rethinking-android-app-compilation-with-buck/.
Essentially, using the list of used classes, we can compile only
the dependencies that are really affected by the developer's
code changes and improve Kotlin build speed.
