Also: make sure that all SkPDF unit tests are named SkPDF_* to
make testing changes to SkPDF easier. Other cleanup.
Add test: SkPDF_pdfa_document to verify that flag in public API
works.
SkPDF_JpegIdentification test: test slightly malformed JPEGs to
verify that all code paths work.

This seems to fix text extraction on Adobe Reader
- Registry/Ordering is now set to Skia/SkiaOrdering.
- Type3 fonts now get a FontDescriptor (force symbolic font).
- CMapName is now Skia-Identity-SkiaOrdering
- CMap behaves correctly for single-byte fonts.
Also:
- SkTestTypeface returns tounicode map for testing.
- Unit test updated
All PDFs render the same

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.

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.
No public API changes.

When possible use run-time checks (via SkDocument::CreatePDF)
When PDF is disabled, do not compile tests/PDF*.cpp
