Merge 64-bit LoongArch LSX and LASX inline assembly implementations from rotate_lsx.cc, rotate_lasx.cc, row_lsx.cc, row_lasx.cc, and scale_lsx.cc into compare_la.cc, rotate_la.cc, row_la.cc, and scale_la.cc, and remove the obsolete loongson_intrinsics.h header. Because all LSX and LASX kernels use inline assembly rather than compiler intrinsics, separate libyuv_lsx/libyuv_lasx build targets and -mlsx/-mlasx compiler flags are no longer required. Guard HAS_*_LSX and HAS_*_LASX macros with defined(__loongarch_lp64) so runtime CPU dispatch enables LASX and LSX without requiring global -mlasx/-mlsx flags, and wrap every function and helper in *_la.cc with its corresponding #ifdef HAS_* guard. Also fix bugs found during LoongArch verification: - Replace illegal vldi/xvldi -1 immediate encodings (si13 = 0x1fff, which raises SIGILL at runtime) in ARGBDetectRow_LSX and ARGBDetectRow_LASX with vseqi.b/xvseqi.b -1. - Set simd_size to 16 for LSX and 32 for LASX in ComputeHammingDistance and ComputeSumSquareError. - Remove orphaned dead BGRAToUVRow, ABGRToUVRow, RGBAToUVRow, and XRGBToUVHelper functions in row_la.cc. - Remove dead alpha shifts in ARGB1555ToYRow/UVRow_LSX/LASX and hoist channel masks out of the loop in RGB565ToUVRow/ARGB1555ToUVRow.

libyuv is an open source project that includes YUV scaling and conversion functionality.
- Scale YUV to prepare content for compression, with point, bilinear or box filter.
- Convert to YUV from webcam formats for compression.
- Convert to RGB formats for rendering/effects.
- Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
- Optimized for SSSE3/AVX2 on x86/x64.
- Optimized for Neon/SVE2/SME on Arm.
- Optimized for MSA on Mips.
- Optimized for RVV on RISC-V.
