  [AArch64] Implement intrinsics for SME2 FSCALE (#100128)

This patch implements these intrinsics:

FSCALE SINGLE AND MULTI
``` 
  // Variants are also available for:
  // [_single_f32_x2], [_single_f64_x2],
  // [_single_f16_x4], [_single_f32_x4], [_single_f64_x4]
  svfloat16x2_t svscale[_single_f16_x2](svfloat16x2_t zd, svfloat16_t zm) __arm_streaming;

  // Variants are also available for:
  //  [_f32_x2], [_f64_x2],
  //  [_f16_x4], [_f32_x4], [_f64_x4]
  svfloat16x2_t svscale[_f16_x2](svfloat16x2_t zd, svfloat16x2_t zm) __arm_streaming
