  [Media] Adopt WTF::flatMap in CDMInstanceFairPlayStreamingAVFObjC
https://bugs.webkit.org/show_bug.cgi?id=261794
rdar://115758431

Reviewed by Richard Robinson.

Replaced the nested for loops in CDMInstanceSessionFairPlayStreamingAVFObjC::contentKeyGroupDataSourceKeys
with a combination of WTF::flatMap and WTF::compactMap. To support RetainPtr<AVContentKey> in compactMap,
also specialized CompactMapTraits for RetainPtr and added tests.

* Source/WTF/wtf/Vector.h:
(WTF::CompactMapTraits<RetainPtr<T>>::hasValue):
(WTF::CompactMapTraits<RetainPtr<T>>::extractValue):
* Source/WebCore/platform/graphics/avfoundation/objc/CDMInstanceFairPlayStreamingAVFObjC.mm:
(WebCore::CDMInstanceSessionFairPlayStreamingAVFObjC::contentKeyGroupDataSourceKeys const):
* Tools/TestWebKitAPI/TestWebKitAPI.xcodeproj/project.pbxproj:
* Tools/TestWebKitAPI/Tests/WTF/cocoa/VectorCocoa.mm: Added.
(TestWebKitAPI::mapString):
(TestWebKitAPI::TEST):
