accommodate for mutiple copies of bind in ckbm

Fixed critical regression where bound parameter tracking as used in the SQL
caching system could fail to track all parameters for the case where the
same SQL expression containing a parameter were used in an ORM-related
query using a feature such as class inheritance, which was then embedded in
an enclosing expression which would make use of that same expression
multiple times, such as a UNION. The ORM would individually copy the
individual SELECT statements as part of compilation with class inheritance,
which then embedded in the enclosing statement would fail to accommodate
for all parameters. The logic that tracks this condition has been adjusted
to work for multiple copies of a parameter.

Fixes: #6391
