Add a FixedZeroedDataVector container.

This is a simple container to hold data of a fixed size. Unlike
FixedUninitDataVector, it does initialize the underlying memory. Since
it always initializes the memory to all zeroes, it does so more
efficiently than std::vector in debug builds. Its public methods are
very limited and generally requires callers to get to the underlying
data via spans.
