spec: unsafe.Add/Slice are not permitted in statement context

Add unsafe.Add and unsafe.Slice to the list of built-in functions
which are not permitted in statement context. The compiler and
type checker already enforce this restriction, this just fixes
a documentation oversight.

For #19367.
For #40481.
