HEVC: Added bit depth change support in decoder reconfiguration. (#527)

* * rocDecode/HEVC: Added bit depth change support in decoder reconfiguration.

* * rocDecode/HEVC: Removed a comment line.

* * rocDecode/HEVC: Updated change log.

* * rocDecode/HEVC: Used the reserved space in RocdecReconfigureDecoderInfo structure for bit_depth_minus_8 field to be backward compatible. Added bit depth to the new sequence file name when we dump output in decoder reconfiguration case.
