  1. Fix silent-duplicate-symbol-resolution of ATen symbols 

    ATen kernels are compiled once for each vectorization level. Since they have the same symbol-names, the linker can make the entire library use the version it finds first.

# Thus we organize the input files in the following order:
 1. All files with no AVX support
 2. All files with AVX support (conveniently, they all have names ending with
    'AVX.cpp')
3. All files with AVX2 support ('*AVX2.cpp')
4. # 3. All files with AVX512 support ('*AVX512.cpp')

    [skip ci]

Permutes after `hadd` & `hsub` weren't required.
Since float `hsub` & `hadd` aren't used elsewhere, we can rename them to signify that it's different from the `hsub` & `hadd` of intrinsics.
However, double `hsub` & `hadd` directly correspond to their respective intrinsics namesakes.

  2. Add AVX512 code to quantized kernels. 

    [skip ci]

Apart from adding AVX512 support to some kernels, some hard-coded values in kernels were made generic.

`qadaptive_avg_pool2d_nhwc_kernel` & `qavg_pool2d_nhwc_kernel` couldn't be enabled for AVX512, as the existing implementation is specifically for AVX2, so I'd have to understand the code deeply.
