Converting orientation handler classes to kotlin
This conversion is a first step for the alignment bug fix and cleanup of the fake orientation classes. The goal is to have these classes following the new architecture using Kotlin, smaller, and testable.
Bug: 320314835
Bug: 328028913
Flag: N/A
Test: presubmit. manual.
