OrderedDict is a subtype of dict, so we can check for a more general form.

Plain dict remembers insertion order since Python 3.6, but it wasn't
formally promised until 3.7.
Can we simply ditch OrderedDict entirely?
In theory, our build requirement is "Python >= 3.6", not
"CPython >= 3.6". In practice, I don't expect anybody to ever
use any other Python implementation except CPython to build QEMU.
I think we can get rid of OrderedDict if you really want to.
No harm in keeping it right now either, it doesn't make typing harder.
The OrderedDict is created in the parser, so we can cover ditching
OrderedDict when we get to that module if desired.
