fix(windows): fix double free (STATUS_HEAP_CORRUPTION) of resizing handler's userdata (#13968)

* fix: double free of resizing handler's userdata on Windows

Using WM_NCDESTROY instead of WM_DESTROY is more correct for freeing userdata, as windows can receive multiple WM_DESTROY events if they're parented.

* chore: add change entry for resizing handler double-free fix
