  [AArch64] Implement NEON vscale intrinsics (#100347)

This patch implements following intrinsics:

```
float16x4_t vscale_f16(float16x4_t vn, int16x4_t vm)	
float16x8_t vscaleq_f16(float16x8_t vn, int16x8_t vm)
float32x2_t vscale_f32(float32x2_t vn, int32x2_t vm)
float32x4_t vscaleq_f32(float32x4_t vn, int32x4_t vm)
float64x2_t vscaleq_f64(float64x2_t vn, int64x2_t vm)
```
