Revert of SkPDF:  cache metrics once. (patchset #4 id:60001 of https://codereview.chromium.org/2253993002/ )

Reason for revert:
because

Original issue's description:
> SkPDF:  cache metrics once.
>
> Motivation: drawText can look up unicode mapping at draw time to see
> if ActualText should be used after crrev.com/2084533004 lands.
>
> For each SkTypeface, only call getAdvancedTypefaceMetrics() once per
> document.  Cache the result in the SkPDFCanon, indexed by SkFontID.
> Also cache PDF FontDescriptors in the canon, also indexed by SkFontID
> (Type1 fonts only).
>
> Simplify PDF font lookup, map SkFontID+SkGlyphID into a uint64_t.  Map
> that uint64_t to SkPDFFonts.  Remove SkPDFCanon::findFont(),
> SkPDFCanon::addFont(), SkPDFFont::IsMatch(), and enum SkPDFFont::Match.
>
> SkPDFFont no longer holds on to ref of SkAdvancedTypefaceMetrics.
> Instead, SkPDFFont::GetFontResource() and SkPDFFont::getFontSubset()
> get metrics from canon.
>
> SkPDFFont multybite bool is now a function of type.
