Remove SimdVisitorWithContext default trait implementation

Removed because `SimdVisitor`'s default implementation causes issues.
It will be automatically implemented for types that may want to implement
`SimdVisitorWithContext` and thus cause them to automatically implement
the default trait implementation. Since there can only be one
trait implementation per type, this effectively prevents the use
of the new trait.
