Accommodate escaped_bind_names for defaults/insert params

Fixed issue in Oracle dialect where using a column name that requires
quoting when written as a bound parameter, such as ``"_id"``, would not
correctly track a Python generated default value due to the bound-parameter
rewriting missing this value, causing an Oracle error to be raised.

Fixes: #7676
