  -----------
  [clang][ASTImporter] Fix a bug when importing CXXDefaultInitExpr.

The "in-class initializer" expression should be set in the field of a
default initialization expression before this expression node is created.
The `CXXDefaultInitExpr` objects are created after the AST is loaded and
at import not present in the "To" AST. And the in-class initializers of
the used fields can be missing too, these must be set at import.

This fixes a github issue #54061.
