JVET-AA0054 Proposal 1: Signaling of external URI information in neural network post-filter characteristics SEI message

Get PTL from VPS in case of Multi-layer OLS.

Refactor ProfileLevelTierFeatures::extractPTLInformation to accept PTL
from VPS, not only from SPS.

When vps_pt_present_flag[i] == 0, infer Profile, Tier and constraint
info for i-th PTL to be the same as that for (i-1)-th PTL.

Ticket #1552

With msg level ERROR the message is printed to stderr

Bugfix for bugs 1 and 3 described in Y0190.
With adoption of Y0237 option C, legal bitstreams now and in the future cannot set gci_num_additional_bits to values in the range 1 to 5.
Decoder behaviour if it encounters such values is non-normative.

Align VTM with spec: fix inference value of pps_scaling_win_xxx_offset (equal to conformance window when not present).
