KSP Migration (#35)

* Start migrating to build.gradle.kts; create ksp module

* Get ksp to running-but-failing-in-tests state

* Reimplement source code analysis for KSP

* Fix basic activity generation

* Re-add fragment, service, and stub support

* Remove kapt implementation

* Fix Robolectric warning; suppress unused warnings in stubs

* Allow source level opt-in; switch to kotlin-parcelize plugin

* Update config/ci to be closer to other juul oss repos

* Add gradlePluginPortal() for org.jetbrains.trove4j:trove4j:20160824

* Fix Kotlinter issues

* More fixes in ci and gradle scripts

* Generate params class with @AsStub instead of @FromStub

This was done to solve issues with stubs across multiple modules. KSP
was not properly carrying annotation arguments across the module
boundary (that is, even though we could see annotations on the stub
class, @Exercise.params was artificially empty).

* Update KSP to alpha 6 and small cleanups
