Narayan Kalaburgi 0aa9a2566f libhevcdec: Fix HBD transquant bypass decoding mismatch 
When transquant bypass is enabled in HBD streams, decoded frames
mismatched the reference output due to two issues:

1. Intra boundary filtering:
   In the 8-bit path, boundary filtering for horizontal (mode 10) and
   vertical (mode 26) intra predictions is disabled when transquant bypass
   is active with implicit RDPCM. However, the HBD reconstruction path was
   passing raw u1_luma_pred_mode instead of disable_boundary_filter, and the
   HBD filter functions ignored the mode parameter.

2. SAO Scratch Buffer Overflow:
   During shifted CTB SAO processing, transquant bypass blocks are temporarily
   backed up into pu1_tmp_buf_luma and restored afterwards to keep them lossless.
   In HBD, each sample requires 2 bytes (UWORD16), but the static scratch buffer
   was allocated for 8-bit samples (sizeof(UWORD8)).
   Because the shifted CTB processing window spans beyond standard CTB boundaries
   to handle delayed neighbor boundaries, the 16-bit luma backup exceeded the
   allocated buffer capacity and overflowed into pu1_tmp_buf_chroma. Consequently,
   chroma backup overwrote the luma backup data, resulting in corrupted samples
   upon restoration.

This commit resolves the above issues with the following changes:
- common/ihevc_hbd_intra_pred_filters.c: Check 'disable_boundary_filter' to bypass
  boundary filtering in ihevc_hbd_intra_pred_luma_horz and ihevc_hbd_intra_pred_luma_ver.
- decoder/ihevcd_iquant_itrans_recon_ctb.c: Pass disable_boundary_filter
  to apf_hbd_intra_pred_luma for modes 10 and 26.
- decoder/ihevcd_api.c: Scale SAO temporary scratch buffer allocation
  (pu1_tmp_buf_luma and pu1_tmp_buf_chroma) by sizeof(UWORD16) to prevent
  buffer collision in HBD mode.
