avcodec/msmpeg4: Factor out common RLTable initialization code
Up until now, both the msmpeg4 decoders and encoders initialized several RLTables common to them (the decoders also initialized the VLCs of these RLTables). This is an obstacle to making these codecs init-threadsafe. So move this initialization to ff_msmpeg4_common_init() that already contains this initialization code. This allows to reuse the AVOnce used for initializing ff_v2_dc_lum/chroma_table which automatically makes initializing these RLTables thread-safe.
