Handle ownership changes in InlineTyper

[odersky]

Fixes a part of #13334 which now works for transparent inline.

The minimized example

class Bar

inline def bar(i: Int): Bar =
  new Bar:
    def j = i

class Foo(x: Int):
  def foo = bar(x)

now works also for inline. But the original example fails with an unrelated error (wrong source position). I verified that
this error occurs even with the inliner before the PR if we turn off ownership checking. So the source position error
was simply masked before by the ownership error, which happened before.

I updated #13334 to reflect the new state.
