api: do not log warnings from x265_api_get() on typical failures

applications might use x265_api_get() to probe which bit depths are available,
we do not want to spew warnings during these operations. Also, plumb in main12
here even though we don't expect to have one for some time, it is ok if current
libs allow queries for them
