Jetifier ProGuard improvements
1) Adds support for cases when a single ProGuard rule needs to be
replaced by multiple rules because mappings are not always 1:1.
One of the examples is:
android/support/v4/media/** -> androidx/media/**, android/support/v4/**
2) Adds more automation into ProGuard mapper to be able to automatically
solve some of the simple rules that contain wildcards. The automated
solution sucessfully maps around 80% of the wildcard rules.
3) Adds more rules for cases where toolings is just not smart enough.
This was tested on 600 ProGuard rules aggregated from wild. Single unit
tests also added.
