This CL adds these classes but does not change any functonality or interface
yet. This is in preparation for future CLs. To be used for this:

RTCCertificateGenerator is meant to replace DtlsIdentityStoreInterface and
implementations. In order to continue to support mocking and to help with the
transition, RTCCertificateGenerator gets an interface that it implements (just
like the store has both interface and impl).
PeerConnectionFactoryInterface::CreatePeerConnection will take an
RTCCertificateGeneratorInterface instead of DtlsIdentityStoreInterface. As to
not break Chromium, both versions of CreatePeerConnection need to exist for a
transition period. This will be done by wrapping a store into a generator
wrapper - RTCCertificateGeneratorStoreWrapper.

This is a new way of generating RTCCertificate objects that is meant
to replace DtlsIdentityStoreInterface and all of its implementations
(clean up work).
It is similar to the identity store in that it generates on the worker
thread and does callback on the signaling thread, but:
- It does not generate identities in the background that you did not
ask for (preemptive generation made more sense before certificates
were parameterized, not so much anymore, and ECDSA which will be most
common takes like <=2 ms to generate).
- As such this code is less complicated than the store's code.
- The API is different, it takes Optional<uint64_t> expires and it
returns RTCCertificates, not SSLIdentities.
- It supports a blocking version of GenerateCertificate that can be
called from any thread, necessary for Chrome which can generate
certificates before the signaling/worker threads have been
initialized as WebRTC-threads (Chrome can invoke this version on
the worker thread outside of WebRTC).
This CL does not remove the identity store, only adds the alternative.
Follow-up CLs will start using it, the store will be removed once it
is no longer used anywhere.
