[x265] [arm64] enable luma_hv for all sizes

[Pop, Sebastian]

Hi,

I have seen on a linux-perf profile that interp_hv_pp_c was still called:

   0.98%  ffmpeg_g  libx265.so.200  [.] (anonymous namespace)::interp_hv_pp_c<8, 32, 32>
   0.87%  ffmpeg_g  libx265.so.200  [.] (anonymous namespace)::interp_hv_pp_c<8, 16, 16>
   0.25%  ffmpeg_g  libx265.so.200  [.] (anonymous namespace)::interp_hv_pp_c<8, 64, 64>

That was due to the fact that some of the kernels for luma_hvpp were disabled.
The attached patch enables luma_hvpp for all kernel sizes.
With the patch the profile does not contain calls to interp_hv_pp_c.
