Make absl::Span a tiny bit more consistent.

Add constexper to equivalent absl::Span members as described by
http://open-std.org/JTC1/SC22/WG21/docs/papers/2018/p0122r7.pdf

* Span constructor use consistently delegate to Span(ptr, length)
* Mark more member methods as constexpr.
* Use data() and size() consistently in member methods.
