This makes the constructor and the unchecked create functions
constexpr on the unit classes Timestamp, TimeDelta, Datarate and
DataSize. This allows using the units in constexpr constants.
Unchecked access methods are made constexpr as well. Making them
usable in static asserts.
Constexpr create functions for checked construction is added in
a separate CL.

This prepares for being able to inject network congestion controllers.
And makes it easier to use the units in other parts of the code.
