Several consumers of libyuv do unified sources build where many source
files are #include'd together to make compilation units larger and allow
for more optimization chances. But for LoongArch there is a wrinkle:
LASX and LSX code paths are implemented in separate files, unlike the
other currently supported architectures, and some definitions are
duplicated e.g. struct RgbConstants.
Since the duplicated content is identical across the two files, short of
some bigger refactoring, we can simply place #ifdef guards around the
definitions to fix unified sources build for LoongArch.

Fix errors in ARGBAttenuateRow_LASX and ARGBAttenuateRow_LSX functions
caused by changes in calculation methods.
In addition, add the option to automatically add "-mlsx" and "-mlasx" to
enable SIMD optimization when compiling with cmake on LoongArch
platform.
