vp9: add vp9 decoder tests in dec_slt. [2/2]

PD#OPS-1192

Problem:
In the dec_slt test, since max_pic_h and max_pic_w were not
configured via config at the upper level, the decoding driver
allocated memory according to the maximum resolution supported
by the chip, this will cause the codec_mm to be insufficient
and lead the test to fail.

Solution:
max_pic_h and max_pic_w are configured via the upper sys_info.
