Function `_mm512_maskz_scalef_ph`

#[target_feature(enable = "avx512fp16")]
pub fn _mm512_maskz_scalef_ph(k: __mmask32, a: __m512h, b: __m512h) -> __m512h

Scale the packed half-precision (16-bit) floating-point elements in a using values from b, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
