Fixes #23279

The issue stems from the fact that in Inlining, when reassigning the owners the inlinined argument (with arg.changeOwner in paramBindingDef), due to a quirk in TypeTreeMap (fixed here), the info field of a xa symbol would not be completely remapped, referencing a TypeRef likedefn(correct Symbol, with newly remapped owner).Lifecycle(old and incorrect, with previous owner). This info would then be used in typedValDef in erasure to reassign the ValDef TypeTree, referencing the old, incorrect Symbol from now on. After that, LambdaLift would remap the denotations of class and object Symbols found in the tree, while moving their trees outside of methods. Since no class or object definition referenced the old Symbol, that one would not get remapped. So by the time we generated backend code, the ValDef TypeTree would reference an incorrect location that no longer existed, causing the runtime error later.

The reason why the TypeTreeMap was incorrect was because in situation like this:

  final lazy module val lifecycle#7793: lifecycle#7794 = new lifecycle#7794()
  final module class lifecycle#7794() extends Object#740() {
    this: lifecycle#7793.type =>
    final lazy module val Lifecycle#7799:
      Test2$package#3202.lifecycle#7793.Lifecycle#7800 =
      new Test2$package#3202.lifecycle#7793.Lifecycle#7800()
    final module class Lifecycle#7800() extends Object#740() {
      this: lifecycle#7794.this#7794.Lifecycle#7799.type =>}
  }
  final lazy module val defn#7795: defn#7796 = new defn#7796()
  final module class defn#7796() extends Object#740() { this: defn#7795.type =>
    val Lifecycle#7805: lifecycle#7793.Lifecycle#7799.type =
      lifecycle#7793.Lifecycle#7799
  }
  val xa#7797: defn#7795.Lifecycle#7805.type = defn#7795.Lifecycle#7805
  ()

The remapper would first copy and replace the outermost symbols (including lifecycle#7793, lifecycle#7794, defn#7795, defn#7796, xa#7797), and then separately go through classes definitions. Now we also remap info the second time, with the newly mapped nested Symbols.
