Comprehensive cursor state cleanup to avoid stale data after TDSResetConnection #3148

Conversation

Earlier we were not cleaning up cursor states and hast tables like CursorHashTable and CursorPreparedHandleHashTable at the time of resetting the TDS connection. This lead to cursor leaks and potentially will let users to continue using the cursors from previous connection. To fix this we introduce a reset_cached_cursor function which cleans up all the stale cursor states and resets the cursor handles.
