Replaces 2-dimensional arrays for storing reference samples in
intra prediction with two 1-dimensional arrays. This reduces memory
usage for these buffers from 792KB to 6KB.

Remove fields whRatio and hwRatio from the IntraPredParam
structure when JVET_O0364_PADDING is enabled as they may be needed
only once. When ratios are needed use logs, adds, and shifts
instead of divisions and multiplications.

Add initializer for angularScale when JVET_O0364_PDPC_ANGULAR is
enabled

- Previous name: Reduced Secondary Transform (RST)
- The parameter, LFNST, should be added in cfg file for enabing LFNST, i.e. LFNST = 1

There is a conflict with JVET_M0427_INLOOP_RESHAPER that is triggering a debug assertion that checks that the width is not 1.
