aarch64: Add support for fp8fma instructions
The AArch64 FEAT_FP8FMA extension introduces instructions for
multiply-add of vectors.
This patch introduces the following instructions:
1. {vmlalbq|vmlaltq}_f16_mf8_fpm.
2. {vmlalbq|vmlaltq}_lane{q}_f16_mf8_fpm.
3. {vmlallbbq|vmlallbtq|vmlalltbq|vmlallttq}_f32_mf8_fpm.
4. {vmlallbbq|vmlallbtq|vmlalltbq|vmlallttq}_lane{q}_f32_mf8_fpm.
It introduces the fp8fma flag.
