Decode callback implementation step 3: completion. (#47)

* * rocDecode/HEVC: Filled HEVC picture parameter structures for decode callback. Added some missing inferences in tile size and weighted prediction table parsing.

* * rocDecode/HEVC: Changed CurrPicIdx assignment from POC to pic_idx.

* * rocDecode/HEVC: Rmoved one TODO comment, which has been done.

* * rocDecode/HEVC: Corrected two typos in comment.

* * rocDecode/HEVC: No need to set up scaling lists in decode callback when scaling list is not enabled.
