BlinkMemoyrMgt: Annotate Blink's platform/font with the macros of Allocator

As a step to annotate the macros of Allocator for the Onion Soup, this CL annotates
some classes of //third_party/blink/renderer/platform/font with the macros of
Allocator.

After some analyzes, it was concluded that for the case of FontFallbackList,
FontGlobalContext, FontSelectionValue, FontUniqueNameLookup, OpenTypeVerticalData,
ShapeResult, and UnicodeRangeSet classes, they make sense to use USING_FAST_MALLOC
because they have been used with smart pointers.

In HarfBuzzShaper class, it makes sense to use DISALLOW_NEW because it's used as
a member variable with a reference type.
