Fixed #32893 -- Fixed serialization of models.Model class in migrations.
...
Migrations assumed that an import of the models.Model class must
already be included when it's serialized, but for models with only
custom fields this was not necessarily the case.
Thanks Jaap Joris Vens for the report.

Fixed #32302 -- Allowed migrations to be loaded from regular packages with no __file__ attribute.
...
The migrations loader prevents the use of PEP-420 namespace packages
for holding apps' migrations modules. Previously the loader tested for
this only by checking that app.migrations.__file__ is present. This
prevented migrations' being found in frozen Python environments that
don't set __file__ on any modules. Now the loader *additionally* checks
whether app.migrations.__path__ is a list because namespace packages
use a different type for __path__. Namespace packages continue to be
forbidden, and, in fact, users of normal Python environments should
experience no change whatsoever.

Fixed #31499 -- Stored ModelState.fields into a dict.
...
This allows the removal of its O(n) .get_field_by_name method and many
other awkward access patterns.
While fields were initially stored in a list to preserve the initial
model definiton field ordering the auto-detector doesn't take field
ordering into account and no operations exists to reorder fields of a
model.
This makes the preservation of the field ordering completely superflous
because field reorganization after the creation of the model state
wouldn't be taken into account.

...
Avoids inspecting the exception message, which is not considered a
stable API and can change across Python versions.
ModuleNotFoundError was introduced in Python 3.6. It is a subclass of
ImportError that is raised when the imported module does not exist. It
is not raised for other errors that can occur during an import. This
exception instance has the property "name" which holds the name of
module that failed to import.
