Encoder side bug fix: the encoder speed up in palette (which bypass INTRA mode check in inter slice if palette mode is better than INTER mode)
shouldn't be applied on 4x4 blocks since JVET-N0266 disabled INTER mode in 4x4 blocks.
Without the fix, intra mode will always be skipped in 4x4 blocks in inter slice if IBC is disabled in SPS.

Remove leftover macro guard

Not sure how this got here. Was it added after automated
macro removal?

If we don't even store the VPS at the decoder, at least properly delete it.
