Full support for "desugared" lambdas

[skylot]

New d8 android compiler allows to use Java 8 lambdas, but to make it work on old Android versions d8 convert (desugar) lambdas to synthetic classes and methods.
This issue continues work on lambda inlining started in #467.
Known issues:

• Lambda classes inlined
• Some lambda classes used by INSTANCE static field
• Not all arguments inlined and synthetic fields in inlined classes not removed
• lambda$* methods must be inlined
• lambdas initialized at fields declaration (with anonymous class as a field type)

Note: Inlining Kotlin lambdas change code semantic by removing extend of kotlin.jvm.internal.Lambda. To disable such inlines use flag --no-inline-kotlin-lambda in jadx-cli and option Allow to inline Kotlin Lambdas in jadx-gui.
