avcodec/vlc: Add functions to init static VLCElem[] without VLC

For lots of static VLCs, the number of bits is not read from
VLC.bits, but rather a compile-constant that is hardcoded
at the callsite of get_vlc2(). Only VLC.table is ever used
and not using it directly is just an unnecessary indirection.

This commit adds helper functions and macros to avoid the VLC
structure when initializing VLC tables; there are 2x2 functions:
Two choices for init_sparse or from_lengths and two choices
for "overlong" initialization (as used when multiple VLCs are
initialized that share the same underlying table).
