Simon Willison c16edb2dc4 Better type signatures for compound foreign key columns
New ForeignKeyColumns type alias - a column name or a list/tuple of
column names - used by add_foreign_key(), add_foreign_keys() (via the
ForeignKeyTuple alias, replacing its Any slots) and the
ForeignKeyIndicator union, which it also simplifies. Tuples now
type-check anywhere lists are accepted.

ForeignKey.__post_init__ normalizes tuple columns/other_columns to
lists so direct construction with tuples compares equal to
introspected foreign keys.
