aarch64: add SVE2 FP8DOT2 and FP8DOT4 intrinsics
This patch adds support for the following intrinsics:
- svdot[_f32_mf8]_fpm
- svdot_lane[_f32_mf8]_fpm
- svdot[_f16_mf8]_fpm
- svdot_lane[_f16_mf8]_fpm
The first two are available under a combination of the FP8DOT4 and SVE2 features.
Alternatively under the SSVE_FP8DOT4 feature under streaming mode.
The final two are available under a combination of the FP8DOT2 and SVE2 features.
Alternatively under the SSVE_FP8DOT2 feature under streaming mode.
