[Font Loading] Implement FontFaceSet
https://bugs.webkit.org/show_bug.cgi?id=153348
Reviewed by Simon Fraser.
Source/WebCore:
The CSS Font Loading spec includes a FontFaceSet object which represents
a collection of FontFaces. This patch implements such an object, and
backs it with a vector of FontFaces. Similarly to the FontFace object,
FontFaceSet is separated into a FontFaceSet frontend object and a
CSSFontFaceSet backend object, which actually owns the FontFace objects.
All the interaction with Promises is performed in the frontend object.
This patch does not implement the EventTarget part of the FontFaceSet
API, so the only way to know when a font is finished loading is by using
the associated Promise objects.
The CSS Font Loading spec describes how the Document should vend an
instance of FontFaceSet which represents the font faces currently
associated with the Document. However, that functionality is
forthcoming. Currently, the only way to get a FontFaceSet is to create
one yourself (using the constructor). Therefore, this patch does not
implement the spec's notion of a "CSS-connected font face."

(WebCore::JSFontFaceSet::values):
* css/CSSAllInOne.cpp: Add new files.
* css/CSSFontFace.cpp: We now have a collection of clients (instead of
just one). Also, we need to keep a pointer to our FontFace wrapper.

this function is not optimized. A subsequent patch (which implements
Document.fonts) will optimize this.

(WebCore::FontFaceSet::load): Most of the complexity of loading is
due to the promises involved. Rather than use the Javascript function
Promise.all(), this patch builds a data structure to represent the
promises which need to be resolved. When fonts finish loading, we look
at the data structure to determine which promises to resolve.
