simd/archsimd: define ToMask only on integer vectors

Browse Source 
The ToMask method is for converting an AVX2-style mask
represented in a vector to the Mask type. The AVX2-style mask is
a (signed) integer, so define ToMask only on integer vectors.

Cherry-pick CL 729020 from the dev.simd branch, for Go 1.26.
