The new type PriorityValue is a strong 16-bit integer matching RFC 8831
requirements that can be built from a Priority enum.
The value is now propagated and used by the SCTP transport, but enabling
the feature still requires a field trial for now.

This code looked a bit weird before this CL - probably because of old
refactorings.
In JsepTransport constructor, there is a DCHECK assuring that the RTP
DTLS transport is always present, so it can be passed directly to the
SctpTransport constructor, which avoids having the SetDtlsTransport
method in it.
Also, in the SctpTransport constructor, there was code that would set
the SCTP transport state to `kConnecting` if the DTLS transport was
present, but that was dead code, as it was always `nullptr` inside the
constructor before this CL. With this CL, it's always present, and the
SCTP Transport's state will initially always be `kConnecting` now. Which
is a step to deprecating the `kNew` state that doesn't exist in
https://w3c.github.io/webrtc-pc/#dom-rtcsctptransportstate.
One test case was modified, as it didn't test the reality. The test
created a SctpTransport, registered an observer, and added the DTLS
transport, and expected to receive a "statechange" from `kNew` (which is
not a state that exists in the spec) to `kConnecting`. If the test had
tested the opposite ordering - adding the DTLS transport first, and then
adding an observer, it wouldn't have experienced this. And since in
reality (with the implementation of JsepTransport before and
after this CL), it always adds the DTLS transport before any observer is
registered. So it wouldn't ever be fired, outside of tests.

This code was extracted to make the next following CL easier to review.
This CL simply exposes the getters, setters and callbacks to set the
buffered amount low threshold on a specific SCTP stream. It will be
used in a follow-up CL, but is just boilerplate.

Before this change, calling buffered_amount only included what was
buffered on top of what was already buffered in the SCTP socket. With
the defaults, the SCTP socket can buffer up to 2MB of data (that is not
put on the wire) before the additional external bufferering in
SctpDataChannel will be used. The buffering that I am working on
removing completely.
Until it's removed completely, to avoid the issue reported in
crbug.com/41221056, include the bytes buffered in the SCTP socket to
what is returned when calling RTCDataChannel::buffered_amount.
This means that when this value is zero, it can be safe to know that all
bytes have been sent, but not necessarily acknowledged. And calling
close will not discard any messages.
This is a stopgap solution, but as functional as the proper solution
that removes all additional buffering. Follow-up CLs will merely improve
this solution.
