Suppressing output of initial lost frames causes Non-BE in EVS BASOP

Related to sa4/audio/ivas-basop#667 (closed) in IVAS BASOP project.

The IVAS decoder suppresses the output of initial lost frames and then catches up by outputting zeros. The functionality is not used in EVS float nor in EVS BASOP and causes a BE failure for 26.444 as described in the issue above.

It does not seem to cause an issue in EVS float since the generated output for these frames is zero, and the output zeros matches the reference.

The proposal is to disable this feature in IVAS for EVS operation to keep BE on 26.444. A long-term solution could be to bring this functionality by CR to EVS.
