  1. Distinguish between -Xsource:3migrate and -Xsource:3cross 

    Add documentation to `-Xsource:help`.

-Xsource:3migrate is an alias for `-Xsource:3`, it enables fatal
warnings but doesn't change semantics.

-Xsource:3cross adpots Scala 3 semantics for certain constructs and
skips the warning, for example modifiers of case class apply / copy
methods. Warnings for things that should be addressed because they are
deprecated / unsupported in Scala 3 remain.
