simd/archsimd: add Grouped for 256- and 512-bit SaturateTo(U)Int16Concat, and fix type

They operate on 128-bit groups, so name them Grouped to be clear,
and consistent with other grouped operations. Reword the
documentation, mention the grouping only for grouped versions.

Also, SaturateToUnt16Concat(Grouped) is a signed int32 to unsigned
uint16 saturated conversion. The receiver and the parameter should
be signed. The result remains unsigned.
