`cached_certificates_by_transport_` is used on the network thread, but
can be cleared from the signaling thread. To fix the race where clear
happens at the same time as stats collecting, a mutex is added.
This mutex should very rarely be contended in practise since
ClearCachedStatsReport() typically only happen during renegotiation
(e.g. when someone joins/leaves) and getStats only happens once per
second or less (typically).

According to a pprof, creating RTCCodecStats is one of the places where
we spend the most CPU time in the event of creating hundreds of them:
https://screenshot.googleplex.com/B6QNDvvoX8dK5vk
The lifetime was recently updated so that we no longer have to risk
creating hundreds of them, here is the relevant section:
https://w3c.github.io/webrtc-stats/#codec-dict*
This allows code simplifications and the deletion of
ProduceCodecStats_n since we can now do a lazy instantiation of codec
stats at the point of being referenced.

Unlike the cache of the entire stats report which is time limited, this
certificate cache is valid for an unlimited amount of time, but is
cleared at ClearCachedStatsReport() which is already called on each
SLD/SRD call. Since certificates can only change by negotiation, this
cache is ensured to always be invalidated when certificates change.
Since ClearCachedStatsReport() can happen for other reasons than
certificates changing we may clear the cache more often then is
necessary, but arguably this is seldom enough that we don't have to
create a separate "ClearCertificateStats()" method. Keep it simple?
The cache specifically avoids rtc::SSLCertChain::GetStats which
trigger rtc::SSLCertificate::GetStats and rtc::Base64::EncodeFromArray.

In non-BUNDLE use cases, it is possible for multiple RTP streams to have
the same SSRC (as long as the SSRC is unique within the same transport).
This CL adds support for "outbound-rtp" and "inbound-rtp" stream stats
to have the same SSRC on different transports by adding the transport to
the stats ID. This avoids multiple RTP stream stats having the same
stats ID and fixes the problem. It's a stupid use case, but it should
work.
There could still be a stats ID collision in the event of multiple
"remote-inbound-rtp" or "remote-outbound-rtp" reference the same SSRC
but on separate transports for the same reason, and would require the
same fix... but one bug at a time. Not addressed in this CL.

To properly handle SSRC collisions in non-BUNDLE we need to change how
RTP stats IDs are generated, but that is a riskier change to be dealt
with in a separate CL.
For now, we just make sure that crashing is not a possibility during
SSRC collisions as a mitigation for https://crbug.com/1361612. This is
achieved by adding a TryAddStats() method to RTCStatsReport returning
whether successful.

The spec says: "Represents the total number of connectivity check
requests sent (not including retransmissions)."
I was surprised to find candidate-pair.requestsSent wired up to
`sent_ping_requests_before_first_response`, which is the subset of
`sent_ping_requests_total` that happened when `recv_ping_responses`
was 0. This is not what the spec says.
By wiring it up to `sent_ping_requests_total` instead, the modern
getStats implementation of "requestsSent" will match the legacy
getStats implementation which is already wired up to this value.

The code incorrectly assumed that codecs exist on a per-mid/transceiver
basis, but codec payload types are unique on a per-transport basis and
in practise most applications use BUNDLE (single transport for the
entire PC).
This CL makes the codecs per-transport instead of per-transceiver. We
still need to iterate transceivers because codecs are exposed on a
per-transceiver basis and as shown in
https://jsfiddle.net/henbos/7kqxgnr8/ it is possible for FMTP lines to
be different on different m= sections despite BUNDLE.
Manual testing shows that this CL brings down the number of "codec"
stats in Google Meet 50p from 872 objects to 43 objects.
