Instead of mapping invaid glyphIDs to zero or maxGlyphID,
don't draw them at all.
Validate glyphs when glyph is written, not ahead of time.
Don't allocate array to copy user-provided glyphs.
Easy early exit from SkPDFDevice::internalDrawText()
GlyphPositioner::flush() called ~GlyphPositioner()
SkScopeExit class now exists.
Assume SkTypeface* pointers are now never null in more
places.
precalculate alignmentFactor to clean up code.
SkPDFDevice::updateFont must be called with validated
glyphID. Skip bad glyphs to make this true.
SkPDFDevice::updateFont always succeeds.
SkPDFFont::GetFontResource always succeeds (preconditions are
asserted). If GetMetrics fails, don't call GetFontResource.
SkPDFFont::glyphsToPDFFontEncodingCount() becomes
SkPDFFont::countStretch() and is inlined.
SkPDFFont::glyphsToPDFFontEncoding now works one Glyph at a
time and is inlined.
SkPDFFont::noteGlyphUsage() operates one glyph at a time.
Add SkScopeExit.h; also a unit test for it.
SkPostConfig: Fix SK_UNUSED for Win32.

Also, rename SK_SFNTLY_SUBSETTER to SK_PDF_USE_SFNTLY

When Skia is built into the Android framework,
SK_SFNTLY_SUBSETTER="sample/chromium/font_subsetter.h".
This #includes the same value for GOOGLE3.
Once Chrome is also using this value, we can do away with
the `#ifdef GOOGLE3` line.

Motivation: gross code simplification, also no bitset lookups at draw time.
SkPDFFont owns its glyph useage bitset.
SkPDFSubstituteMap goes away.
SkPDFObject interface is simplified.
SkPDFDocument tracks font usage (as hash set), not glyph usage.
SkPDFFont gets a simpler constructor.
SkPDFFont has first and last glyph set in constructor, not adjusted later.
SkPDFFont implementations are simplified.
SkPDFGlyphSet is replaced with simple SkBitSet.
SkPDFFont sizes its SkBitSets based on glyph count.
SkPDFGlyphSetMap goes away.
SkBitSet is now non-copyable.
SkBitSet now how utility methods to match old SkPDFGlyphSet.

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.

Keep isOpaque as a convenience method -- many places really only need to
know that for optimization purposes (SrcOver -> Src, etc...).
In all the places where we pull data back out or convert to another
object and need to supply an SkImageInfo, we can avoid losing information
about premulness.

SkPDFFont:
* inline some one-line methdods.
- SkPDFFont::typeface()
- SkPDFFont::fontInfo()
- SkPDFFont::firstGlyphID()
- SkPDFFont::lastGlyphID()
- SkPDFFont::getFontDescriptor()
* de-virtualize some methods:
- SkPDFFont::getType()
- SkPDFFont::multiByteGlyphs()
* Constructor takes more arguments:
fontType, multiByteGlyphs
* re-order fields (pointers before shorts)
* use sk_sp<T> more, T* less
SkAdvancedTypefaceMetrics:
* SkAdvancedTypefaceMetrics::fFont now a uint8_t
* other enumes are sized.
* SkAdvancedTypefaceMetrics::fStyle now big enough.
* remove use of SkTBitOr, replaced with fancy templates

SkPDFFont:
- SkPDFType1Font::populate() encode advances correctly.
- break out logically independent code into new files:
* SkPDFConvertType1FontStream
* SkPDFMakeToUnicodeCmap
SkPDFFont.cpp is now 380 lines smaller.
Expose `SkPDFAppendCmapSections()` for testing.
SkPDFFontImpl.h
- Fold into SkPDFFont.
SkPDFConvertType1FontStream:
- Now assume given a SkStreamAsset
SkPDFFont:
- AdvanceMetric now hidden in a anonymous namespace.
