support 2.0 style variants

Implemented support for recognizing and rendering SQLAlchemy "variant"
types going forward into SQLAlchemy 2.0, where the architecture of
"variant" datatypes will be changing.

Specifically any TypeEngine can now have "variants" by looking
in the _variant_mapping dictionary collection associated with the
type directly.
