use clone, not constructor, in BindParameter.render_literal_execute()

use clone, not constructor, in BindParameter.render_literal_execute()

Fixed issue where the :meth:`_sql.BindParameter.render_literal_execute`
method would fail when called on a parameter that also had ORM annotations
associated with it. In practice, this would be observed as a failure of SQL
compilation when using some combinations of a dialect that uses "FETCH
FIRST" such as Oracle along with a :class:`_sql.Select` construct that uses
:meth:`_sql.Select.limit`, within some ORM contexts, including if the
statement were embedded within a relationship primaryjoin expression.

Fixes: #9526
