Reviewed by Chris Dumez.

Source/WebCore:

Chris and Alex requested this alternate style, where the enum class for each enumeration
goes inside the class for the interface the enumeration is used in. Also made a rule that
keeps the names short and not redundant with the class name they are nested in.

* Modules/fetch/FetchOptions.h: Moved all the enum class types into the struct.

* Modules/fetch/FetchRequest.cpp:
(WebCore::setReferrerPolicy): Updated.
(WebCore::setMode): Ditto.
(WebCore::setCredentials): Ditto.
(WebCore::setCache): Ditto.
(WebCore::setRedirect): Ditto.
(WebCore::buildOptions): Ditto.
(WebCore::buildHeaders): Ditto.
(WebCore::FetchRequest::create): Ditto.
* Modules/fetch/FetchRequest.h: Used "using" to repeat the types from FetchOptions
here in FetchRequest. That way the generated bindings can find the types, and we don't
need to do any trick like [ImplementedAs] in thd IDL to make it work.

* Modules/fetch/FetchResponse.cpp:
(WebCore::FetchResponse::error): Updated.
(WebCore::FetchResponse::redirect): Ditto.
(WebCore::FetchResponse::FetchResponse): Ditto.
(WebCore::FetchResponse::startFetching): Ditto.
* Modules/fetch/FetchResponse.h: Moved enum class into the class.

* Modules/mediacontrols/MediaControlsHost.cpp:
(WebCore::MediaControlsHost::externalDeviceType): Updated.
* Modules/mediacontrols/MediaControlsHost.h: Moved enum classs into the class.

* Modules/mediasession/MediaSession.cpp:
(WebCore::MediaSession::MediaSession): Updated.
* Modules/mediasession/MediaSession.h: Moved enum classs into the class.

* Modules/mediasource/MediaSource.cpp:
(WebCore::MediaSource::addSourceBuffer): Updated.
(WebCore::MediaSource::removeSourceBuffer): Ditto.

* Modules/mediasource/MediaSource.h: Moved enum class into the class.

(WebCore::SourceBuffer::appendError): Ditto.
(WebCore::SourceBuffer::sourceBufferPrivateDidReceiveSample): Ditto.
(WebCore::SourceBuffer::textTrackModeChanged): Ditto.

* Modules/mediasource/SourceBuffer.h: Removed incorrect forward declaration
of EndOfStreamError that also now seems to be unneeded. Moved enum class into
the class.

* Modules/mediastream/MediaDeviceInfo.cpp:
(WebCore::MediaDeviceInfo::MediaDeviceInfo): Updated.
(WebCore::MediaDeviceInfo::create): Ditto.
* Modules/mediastream/MediaDeviceInfo.h: Moved enum class into the class.

* Modules/mediastream/MediaStreamTrack.cpp:
(WebCore::MediaStreamTrack::readyState): Updated.

(WebCore::processorType): Updated.
(WebCore::WaveShaperNode::oversample): Ditto.
* Modules/webaudio/WaveShaperNode.h: Moved enum class into the class.

(GetAttributeSetterName): Ditto.
(GetFunctionName): Tweaked style.
(AttributeShouldBeOnInstanceForCompatibility): Deleted. Was a function that
always returned 0.
(AttributeShouldBeOnInstance): Removed the call to the function above.
(IsClassNameWordBoundary): Added. Helper for function below.
(IsPrefixRemovable): Ditto.
(GetEnumerationClassName): Added an $interface argument and changed this
so it creates a nested name inside the class rather than a top level name
for use at the WebCore namespace level.
(GetEnumerationClassIdentifier): Added. Calls GetEnumerationClassName and
makes a flattened name without "::" that can be used in an identifier.
(GenerateEnumerationImplementationContent): Renamed from GetXXX. Added an
$interface argument, so it can pass that along to the functions above.
(GenerateHeader): Updated to not pass $interfaceName.
(GeneratePropertiesHashTable): Ditto.
(GenerateOverloadedFunction): Removed unneeded $interfaceName argument.
(GenerateImplementation): Updated for changes above. Tweaked formatting.

and made the IsEnumType section call the new functions.

dealing with enumerations.

of the logic above.

(WebCore::CryptoKey::CryptoKey): Updated.
(WebCore::CryptoKey::usages): Ditto.

CryptoKeyUsage and CryptoKey::Usage.

(WebCore::FontFace::status): Updated.
* css/FontFace.h: Moved enum class into the class.

* css/FontFaceSet.cpp:
(WebCore::FontFaceSet::status): Updated.

to work around what is apparently a bug in the IDL parser.

changed ReferrerHeaderPolicy back to ReferrerPolicy.
* page/SecurityPolicy.h: Ditto.

* platform/ReferrerPolicy.h: Changed ReferrerHeaderPolicy name back
to ReferrerPolicy now that nesting inside a class eliminated the conflict;
still should merge them and that FIXME remains.

* testing/Internals.idl: Removed the "Internals" prefixes we added
to resolve ambiguity before. Nesting these in the class now takes care
of the ambiguity instead.
