wasm: Add missing #[target_feature] to simd ctors

Browse Source 
This is a resubmission of #1609 which was ruled optional but not
necessary at the time but it's now necessary. These weren't originally
applied as they weren't allowed in a `const` context but that's no
longer applicable. At the same time though be sure to add some small
tests to ensure that these intrinsics can be used in a `const` context.
