1. enabling the encoder-side RD check of ISP mode when ACT is disabled at CU level
2. ACT intra RD code clean-up

 Added back sps_temporal_mvp_enabled_flag to align with specification text in JVET-O2001-vE. \n This also means that sps_sbtmvp_enabled_flag can be signaled in SPS as before instead of in PPS.

This reverts commit 8e16ada0.

Use vectors and resize them if needed instead of deleting and
reallocating memory for every picture. This appears to have a
significant impact on decoder run time.

Use PLTRunMode type where appropriate instead of bool since
using vector<bool> creates a number of issues

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.

initial commit of JVET_O0119_BASE_PALETTE_444: palette in HEVC and palette mode coding in JVET-N0258

use m_pcEncCfg->getUseAffineAmvrEncOpt() to control the effect of m_pcEncCfg->getIntraPeriod() != ( uint32_t ) -1, i.e., low delay setting.

- The parameter, LFNST, should be added in cfg file for enabing LFNST, i.e. LFNST = 1
