[AArch64] Add missing "+i8mm" feature when building SME

FEAT_I8MM is not unconditionally enabled with -march=armv9-a since it
only becomes mandatory from Armv9.1-A, so explicitly specify it in both
BUILD.gn and CMakeLists.txt.

Also flip the order of +sve2+i8mm => +i8mm+sve2 to match occurrences
elsewhere.

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.
