Fixed #35870 -- Made blank choice label in forms more accessible.

Added new constant django.db.models.fields.BLANK_CHOICE_LABEL for
an accessible and translatable blank choice label in forms.
Deprecated django.db.models.fields.BLANK_CHOICE_DASH constant.
Added the immediately deprecated transitional setting
USE_BLANK_CHOICE_DASH.
