Restrict libyuv_use_sme to is_linux

When libyuv is used in Chrome, there are linker errors or other build
errors on the following platforms:
- Android: undefined symbol: __getauxval
- Fuchsia: undefined symbol: __aarch64_sme_accessible
- macOS: undefined symbol: __arm_tpidr2_save
- Windows: Incorrect size for TransposeWxH_SME prologue: 52 bytes of
  instructions in range, but .seh directives corresponding to 40 bytes

Restrict libyuv_use_sme to is_linux (which excludes Android and
ChromeOS) to work around these errors.

  • 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 on Arm.
  • Optimized for MSA on Mips.
  • Optimized for RVV on RISC-V.
