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.

Fixed #24559 -- Made MigrationLoader.load_disk() catch more specific ModuleNotFoundError.
...
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.

Refs #28305 -- Consolidated field referencing detection in migrations.

This moves all the field referencing resolution methods to shared

references methods.
