I strongly support removing FeatureList.pm since it's useless for 
keeping build definitions in sync between XCode and CMake, and it 
complicates things unnecessarily for both XCode and CMake.

There is one very minor complication. GTK and WPE currently use the 
FeatureList.pm features as "developer features" since our bots all use 
the build-webkit script, so we have some features enabled there that we 
don't have enabled in WebKitFeatures.cmake. I think right now that is 
just MSE and WebRTC. This means that we'll need to adjust our buildbot 
configurations to manually enable these features at the same time that 
FeatureList.pm is removed to avoid breaking all these tests.
