avcodec/msmpeg4dec: Avoid lookups when decoding motion vector

Up until now, the decoder uses VLCs to determine whether this is an escape element or an index in two separate tables giving the x and y components of the motion vector. Given that both these components fit into an int16_t and therefore into a VLCElem's symbol one can simply use a symbol table to avoid the latter lookups. This necessitated to combine the two tables for x and y components. While just at it, also switch to ff_vlc_init_tables_from_lengths(). This will allow to get rid of the code tables (about 4KiB) once the encoder has been ported, too.
