Remove manual mixins in JFunctionN.v2.12.0-M3-dc9effe

These manual mixins were forwarding to the impl classes have
just been removed. We can now rely on default methods instead.

Update Tests:

 - Fix test/files/pos/t1237.scala, we can't have an outer field
   in an interface, always use the outer method.
 - Don't crash on meaningless trait early init fields
   test/files/neg/t2796.scala
 - Remove impl class relate parts of inner class test
 - Remove impl class relate parts of elidable test
 - Remove impl class related reflection test.
 - Remove test solely about trait impl classes renaming
 - Update check file with additional stub symbol error
 - Disable unstable parts of serialization test.
    - TODO explain, and reset the expectation
