Negative infinity is useful in comparisons as it represents a value
guaranteed to be less than any other timestamp. This avoid using
Timestamp::ms(0) to represent such a value or having to use optional
for the special case of first time execution.
To avoid ambiguity, Timestamp::Infinity is renamed to PlusInfinity.

This prepares for allowing use making arithmetic operators constexpr.
This also makes it easier to use for comparisons with offsets.
Now a > b + 10 ms works even if b is infinite.

This adds new constexpr create function for DataSize, DataRate,
TimeDelta and Timestamp. The names are capitalized to mirror the
naming scheme of the previously constexpr methods (Zero and
Infinity create functions). They are also kept longer since they
are not expected to be used in complex expressions.

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.

The behavior of division-by-zero is undefined, so the DivisionByZeroFails test isn't correct. As we don't need any specific behavior on division-by-zero we leave the current code untouched.
Additionally, since the DivisionFailsOnLargeSize EXPECT_DEATH checks rely on DCHECKs, we only run those when DCHECKs are enabled.

This removes the redundant type and replaces all usages. A slight change
in behavior is that we no longer get nanosecond resolution. This should
not matter since no current code requires nanosecond resolution.

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