  [AArch64] Add intrinsics support for multi-vector FMUL (#163397)

This patch adds intrinsics for multi-vector FMUL instructions introduced
in armv9.6, based on
[this](https://github.com/ARM-software/acle/pull/412) ACLE proposal.

Depends on #163536

Intrinsics implemented:

//BFMUL:
svbfloat16x2_t svmul[_bf16_x2](svbfloat16x2_t zd, svbfloat16x2_t zm) __arm_streaming;
svbfloat16x2_t svmul[_single_bf16_x2](svbfloat16x2_t zd, svbfloat16_t zm) __arm_streaming;
svbfloat16x4_t svmul[_bf16_x4](svbfloat16x4_t zd, svbfloat16x4_t zm) __arm_streaming;
svbfloat16x4_t svmul[_single_bf16_x4](svbfloat16x4_t zd, svbfloat16_t zm) __arm_streaming;
