Replace internal uses of BlinkMacSystemFont on Mac with system-ui
This patch replaces internal uses of "BlinkMacSystemFont", Blink's
non-standard extension on Mac, with the standard "system-ui" generic
font family.
By eliminating internal uses, the aliasing is moved from FontCache
to CSS resolving time. This allows access to the document, which is
needed for per-document use counter.
