Frank Barchard 3fbdc763b0 [libyuv] Remove all x86 SSE optimizations 
Removed all SSE functions, macros, dispatching logic, and related
unit tests across the repository to reduce code size and complexity.
Left cpuid detection intact. Supported architectures like AVX2, NEON,
SVE, etc. are unaffected.
