[c2][encoder] Fix AV1 encoder issue

Fix AV1 encode issue of "Encoder configure failed" and test be
always waiting and can not run to end when running ffmpeg.

"Encoder configure failed" is because in mfx_set_RateControlMethod
function AV1 encoder case in not handled.

Test always wait and can't run to end is because GopRefDist is not
set when initializing AV1 encoder, default value of 8 from vpl is
used, which caused mediasdk_c2 can't send work done notification
to framework codec, so framework codec can't queue more works after
queuing initial 4 works.

Besides, use PROFILE_AV1_0 & LEVEL_AV1_5_3 as default AV1 encoder
profile & level instead of PROFILE_AV1_0 & LEVEL_AV1_7_3, as the
latter can not work.
