SkPDF: Glyph Useage Map improvements
Instead of having a fFontGlyphUsage on each device and one on each
document, just have the one on the document, and never merge.
Make fGlyphUsage accesible on SkPDFDocument.
Remove SkPDFGlyphSetMap::merge, ::reset, and SkPDFGlyphSet::merge.
SkPDFGlyphSetMap has an TArray of SkPDFGlyphSet, not TDArray of
SkPDFGlyphSet pointers. SkPDFGlyphSet and SkPDFBitset get move
constructors.
All tests produce exactly identical output PDFs.
