Support "blank" schema when MetaData.schema is set
Previously, it was impossible to have a Table that has
None for a schema name when the "schema" parameter on
MetaData was set. A new symbol sqlalchemy.schema.BLANK_SCHEMA
is added which indicates that the schema name should unconditionally
be set to None. In particular, this value must be passed within
cross-schema foreign key reflection, so that a Table which
is in the "default" schema can be represented properly.
Fixes: #3716
