Add typing of django.db.migrations.autodetector

[JaeHyuckSa]

I have made things!

I added the typing of 'django.db.migrations.autodetector'.

• django.db.migrations.autodetector.MigrationAutodetector
  • django.db.migrations.autodetector.MigrationAutodetector.create_altered_constraints
  • django.db.migrations.autodetector.MigrationAutodetector.create_renamed_fields
  • django.db.migrations.autodetector.MigrationAutodetector.generate_added_constraints
  • django.db.migrations.autodetector.MigrationAutodetector.generate_altered_db_table_comment
  • django.db.migrations.autodetector.MigrationAutodetector.generate_removed_altered_unique_together
  • django.db.migrations.autodetector.MigrationAutodetector.generate_removed_constraints
  • django.db.migrations.autodetector.MigrationAutodetector.generate_renamed_indexes

I've confirmed with version 5.0.4 that the function generate_removed_altered_index_together will indeed be removed in Django version 5.1
