Make "good" quality 2-pass vpxenc encoding default
Currently, the best quality mode in VP9 is not very well developed, and unnecessarily makes the encode too slow. Hence the command line default is changed to "good" quality. Also, the number of passes default is changed to 2 passes as well, since 1-pass encoding is not very efficient in VP9. Besides, a number of VP9 defaults are set to the currently recommended settings. With these changes, vpxenc run with --codec=vp9 --kf-max-dist=9999 --cpu-used=0 should work about the same as our borg results. Note when the --cpu-used=0 option is dropped there will be a slight difference in the output, because of a difference in the cpu-used value for the first pass. Specifically, the default when unspecified is to use cpu_used=1 for the first pass and cpu_used=0 for the second pass. But when specified, both passes will use the cpu-used value specified. Note that this also changes the default for VP8 as being "good" but other options stay unchanged. Change-Id: Ib23c1a05ae2f36ee076c0e34403efbda518c5066
