2c8dc7e953 avcodec/loongarch/h264chroma, vc1dsp_lasx: Add wrapper for __lasx_xvldx
__lasx_xvldx does not accept a pointer to const (in fact,
no function in lasxintrin.h does so), although it is not allowed
to modify the pointed-to buffer. Therefore this commit adds a wrapper
for it in order to constify the H264Chroma API in a later commit.

__lsx_vldx does not accept a pointer to const (in fact,
no function in lsxintrin.h does so), although it is not allowed
to modify the pointed-to buffer. Therefore this commit adds a wrapper
for it in order to constify the HEVC DSP functions in a later commit.

LSX and LASX is loongarch SIMD extention.
