avcodec/la: Add LSX optimization for loop filter. 
Replaced function(LSX is sufficient for these functions):
ff_h264_v_lpf_chroma_8_lasx
ff_h264_h_lpf_chroma_8_lasx
ff_h264_v_lpf_chroma_intra_8_lasx
ff_h264_h_lpf_chroma_intra_8_lasx
ff_weight_h264_pixels4_8_lasx
ff_biweight_h264_pixels4_8_lasx

./configure --disable-lasx
ffmpeg -i 1_h264_1080p_30fps_3Mbps.mp4 -f rawvideo -y /dev/null -an
before: 161fps
after:  199fps
