avcodec/intrax8: Reduce the size of tables used to initialize VLCs
...
By switching from ff_init_vlc_sparse() to ff_init_vlc_from_lengths() one
can replace an array of codes of type uint16_t with an array of symbols
of type uint8_t, saving space.
Also remove some more code duplication while at it.

ptrdiff_t is the correct type for array strides and similar.
