Title: GROOVY-5096: @Immutable should have an extensible way to be informed of ...

...classes that are "deemed" Immutable

This patch adds the "knownImmutables" attribute to @Immutable. The attribute can be used to specify "deemed" immutable classes which will than be treated as predefined immutable classes in ImmutableASTTransformation.
