Add a class to represent a sequence of BalsaHeaders.

This CL introduces BalsaHeadersSequence, which wraps a std::list<BalsaHeaders>
and an iterator. Users add BalsaHeaders to the BalsaHeadersSequence (owning),
and can then get a pointer (non-owning) to successive BalsaHeaders.

The immediate usage of BalsaHeadersSequence will be in SimpleClient
(RequestsTestHelper ecosystem, cl/527686928), but the long-term envisioned use
case will be in JetstreamSession, e.g., adding to BalsaHeadersSequence in the
readers and consuming the BalsaHeaders while driving the response pipeline [1].
