avcodec/webp: Switch to ff_vlc_init_from_lengths()
The earlier code would traverse over the code lengths
mutliple times (namely max_length + 1 times - once to get
the maximum length and once for each max_length to assign
codes) before calling ff_vlc_init_sparse() (which may traverse
them twice and sort them). The new code only traverses them once
(+ the one time in ff_vlc_init_from_lengths()).
