Pass declared-but-yet-undefined DecoderDoctorDiagnostics pointer to various
routines that contribute to deciding if a media format can be played, and
those that create decoders.
Points where a DecoderDoctorDiagnostics can be injected are currently marked
with "/* DecoderDoctorDiagnostics* */ nullptr", and some will be used in
following patches.

We end up showing the "Adobe EME is preffed off" UI on MacOSX because we're
check for Adobe EME support based on platform, not based on whether it's
configured on in the mozconfig. We should really only check for Adobe EME
if 'ac_add_options --enable-eme=adobe' is present in the build config,
as otherwise preffing it on isn't going to work.

The Widevine CDM does not have an AAC decoder. It can however decrypt audio
streams. It's our policy to not decode AAC streams decrypted by the Widevine
CDM with the Adobe GMP's unencrypted decoding functionality. So reject
MediaKeySystemAccess requests for Widevine if we don't have a system AAC
decoder that we can use.

The logic in MediaKeySystemAccess is convoluted because it needs to keep
checking whether we're servicing a clearkey request and whether WMF is
available for gmp-clearkey to decode with. If we instead push those checks down
into GMPParent at the time where we parse the GMP info file, we can just not add
the decode capability to the GMPParent, and can remove the special cases in
MediaKeySystemAccess. This simplifies adding the (similar) special cases for
Widevine in the next patch.

This means we won't try to build it when ac_add_options --enable-eme=widevine is
not present, and critically, we won't try to build it on Android, since the Chromium
Widevine plugin isn't available there.
MozReview-Commit-ID: 1jQvAbJP8HG
We need to not build Widevine by default, and when enabled we will need to be able to
ifdef on MOZ_WIDEVINE_EME (see next patch) so that we can not build the code on platforms
where it can't possibly work (Android specifcally, as Widevine isn't available as a
Chromium plugin there).

All the methods in CDMProxy except CDMProxy::OnExpirationChange() that use
mKeys null check mKeys before using it because it can go away during shutdown
before the IPC message to call the methods have had a chance to run.
We should do the null check in CDMProxy::OnExpirationChange() too.
Remove GMPVideoDecoderTrialCreator, and the tests and IPC/IDL supporting it.

Resurrect WMFDecoderModule::HasAAC() and HasH264(), and use those in
MediaKeySystemAccess.cpp to figure out whether we gmp-clearkey can decode,
rather than assuming Vista and later is always able to decode, as that's not
a valid assumption; Vista may not have the required Platfor Update installed,
or we may be on Windows N or KN without the Media Feature Pack.

part was modifying MFBT's moz.build to reflect the new naming.
