Can't compile with MSVC for Arm64 and __ARM_NEON defined

[divideconcept]

Right now you can't compile Whisper.cpp (1.7.5 and current master) with MSVC for Arm64 and __ARM_NEON defined, due to the __fp16 not being known by MSVC, in ggml-impl.h:

#if defined(__ARM_NEON) && !(defined(__CUDACC__) && __CUDACC_VER_MAJOR__ <= 11) && !defined(__MUSACC__)
    #define GGML_COMPUTE_FP16_TO_FP32(x) ggml_compute_fp16_to_fp32(x)
    #define GGML_COMPUTE_FP32_TO_FP16(x) ggml_compute_fp32_to_fp16(x)

    #define GGML_FP16_TO_FP32(x) ggml_compute_fp16_to_fp32(x)

    static inline float ggml_compute_fp16_to_fp32(ggml_fp16_t h) {
        __fp16 tmp;
        memcpy(&tmp, &h, sizeof(ggml_fp16_t));
        return (float)tmp;
    }

    static inline ggml_fp16_t ggml_compute_fp32_to_fp16(float f) {
        ggml_fp16_t res;
        __fp16 tmp = f;
        memcpy(&res, &tmp, sizeof(ggml_fp16_t));
        return res;
    }
