Spanner uses protos for enums. Creating a column like
Column("an_enum", Enum("A", "B", "C")) will result in a String
column. Setting supports_native_enum to False means SQLAlchemy
will generate check constraints to enforce the enum values
server-side rather than rely on a the database's native enum
type to enforce them.
Fixes: googleapis#686

I'm not sure this change is enough to actually achieve this. Would you otherwise mind adding a test that shows that it does?
I tried the same here, but it does not seem to make any difference: https://github.com/googleapis/python-spanner-sqlalchemy/pull/698/files
