Add an implementation of Result<const T*, E*>

The existing implementation of Result with tagged pointers was not able
to handle constant pointers for the result. This is required in
follow-up CLs to return internal formats in a ResultOrError.

This CL extracts the tagged pointer logic out of Result<T*, E*> so it
can be shared with Result<const T*, E*>.

Tests are also added to cover Result<const T*, E*>.
