Reduce memory consumption when loading AOT generated cache files
Separate the qml data (objects/imports) from the general compilation
unit data. It's only the former that needs to be re-generated as part of
the type re-compilation and by separating it we can allocate memory just
for that and keep using the mmap'ed general unit data for everything
else (including byte code).
Another upside of this change is that it allows eliminating the recently
introduced concept of a backing unit again.
Saves ~149K RAM with the QQC1 gallery.
