This enables us to identify GMPDecryptor instances in the child process, so that
in a later patch when we create a GMPVideoDecoder instance, we can associate it
with a GMPDecryptor. Then the cdm::ContentDecryptionModule8 instance that these
two actors are adapted to can know whom it's supposed to respond to.
We use the IPDL PGMPDecryptorChild actor ID as the GMPDecryptor's ID. This is unique
per GMP process, which is sufficient.

These are done in the GMPProvider, so it's unnecessary to do them again inside
Gecko. Plus, they cause main thread synchronous IPC in multi-process Firefox.

We don't need to call MediaKeys::ConnectPendingPromiseIdWithToken() on the
MediaKeySession::Load() path, we already know the session Id, and we've already
removed the session from the list of pending sessions in Load().

Now that we can link gmp-clearkey's PSSH parser into Gecko, we can
simply use that inside MediaKeySession to validate that the CENC
init data matches the spec.
This change enforces that CENC init data uses the common system Id.
As far as I can tell, Widevine only uses that now.

Use a WebIDL dict to define the "keyids" EME init data format, and
then use that to parse and validate incomint "keyids" EME init data
and ensure it's in the expected JSON format, i.e.:
https://w3c.github.io/encrypted-media/format-registry/initdata/keyids.html
This means we now pass the "generateRequest() with too short key ID."

Implement more of MediaKeySession.generateRequest() to validate initData before
passing to CDM.
Also throw TypeErrors when initData is not valid, as per the spec.
Only trivial validation happens here, I'll add more comprehensive validation in
subsequent patches.

This allows us to track how often EME CDMs are used, rather than just created.
The telemetry I added in bug 1304207 is reports whenever a CDM is created, but
some sites, such as the Shaka Player demo site, create CDMs without using them,
so that telemetry isn't a great measure in helping us detect when CDMs aren't
being used. Whereas the telemetry added here will report when the CDMs are used
to negotiate a license, i.e. when the CDMs are actually being used.

Add opt-out telemetry probe to track which EME CDMs are being instantiated.
This will enable us to determine when it's safe to remove the Adobe CDM.
