Add support for uint16x4x[2-4]_t AArch64 SIMD types (#2779)

This change adds support for `uint16x4x2_t`, `uint16x4x3_t`, and `uint16x4x4_t` AArch64 SIMD types by including them in the `simd_arch_mod!` macro invocation. These types were missing from the supported list, despite `uint16x4_t` being present.
