Add Web API Statistics Collection

<rdar://problem/44155162>

Source/WebCore:
Added data collection for web API statistics, specifically regarding the canvas, font loads,
screen functions, and navigator functions. The data collection code is placed under a runtime
enabled feature flag. The statistics are stored in a ResourceLoadStatistics object and written
to a plist on disk. Added a new file CanvasActivityRecord.h and CanvasActivityRecord.cpp which
includes a struct to keep track of HTML5 canvas element read and writes.

Before, entries in the ResourceLoadStatistics involving HashSets used "origin" as the key.
Now the encodeHashSet function has been generalized to take any key to encode the entries
in the HashSet. Also added functionality to encode an OptionSet by converting it to its
raw bitmask state.
