m_decodingUnitDpbDuParamsInPicTimingSeiFlag was not copied

As in specification: "The value of pt_sublayer_delays_present_flag[ bp_max_sublayers_minus1 ] is inferred to be equal to 1"

Currently m_latestDRAPPOC for pictures which follow DRAP is always MAX_INT.

This prevents checkConformanceForDRAP() from checking active ref pic constraints

It seems that caller of activateAPS() expects that pointers to lmcsAPS and scalingListAPS are updated.

However they are not and then checkParameterSetsInclusionSEIconstraints() does not perform proper checks for LMCS and ScalingList APSs

Add const qualifier where appropriate

When method checkAlfNaluTidAndPicTid() is called for a Slice object
pointers to SPS and VPS are not yet set.

Methods setSPS() and setVPS() are called later for that Slice object.

Since IDs of SPS and VPS are known at this point,
SPS and VPS can be found in ParameterSetManager.
