Fix #80027 Terrible performance using $query->fetch on queries with many bind parameters
Added new flags that allow skipping param_evt(s) that are not used by drivers,
in a backwards and forward compatible manner. Updated the pgsql, mysql, sqlite
and oci drivers to properly use the new flags. I've left out pdo_dblib, which
doesn't have a param_hook, and pdo_firebird, which seems to be using
PARAM_EVT_NORMALIZE in a wrong context (param type vs event type).
