Takuto Ikuta 96134e95a7 BUILD.gn: Disable libc++ modules for NEON and SVE 
The -march arguments used for NEON and SVE builds in libyuv are
incompatible with libc++ modules. This change disables libc++ modules
for these build configurations to fix the build.

README.md

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.
