cuvid: Pass bit depth information to decoder
Although cuvid can only output 8bit, it can consume HEVC Main10 if the bit depth is set properly. In cases where >8bit is not supported, this change is still beneficial as the decoder will fail to be created instead of plowing throw and decoding as 8bit.
