8c662a7d6e Get rid of deprecated API to add children to PDF tag nodes.
fChildren/fChildCount was replaced with fChildVector and Chromium
migrated to the new API a while back, it's now safe to remove the
older interface.

8f233fc795 Add marked-content ID to PDF images
Previously we only added marked-content IDs to text commands.
Extend this to support marking bitmaps drawn to a PDF document
too, so that images can be tagged with alt text.

Moves the code that outputs the marked content ID and closing
tag into a scoped helper class that outputs the closing sequence
on destruction.

Note: we'll probably want to do this to nearly all drawing
commands, since nearly everything could in theory be tagged.

This change is safe because it's still behind a flag in
Chromium and if the document doesn't have any structure
tree, it won't output anything.

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

656cefe65d Add initial support for generating tagged PDFs.
Adds an interface for the document creator to pass in a tree
of tags indicating the structure of the document, each with a type
(from a predetermined enum of possible types) and a node ID.
It also adds a setNodeId function to SkCanvas so that page content
can be associated with a particular tag. If both the tag tree and
marked content are present, Skia can now output a properly tagged
PDF.

An example program is included. When used properly, the PDF generated
by this patch is valid and the tags are parsed properly by Adobe
Acrobat. It handles many corner cases like content that spans more
than one page, or tags that don't correspond to any marked content, or
marked content that doesn't correspond to any tags.

However, it doesn't implement all of the features of PDF accessibility
yet, there are some additional attributes that can be associated with
some tags that need to be supported, too, in order to properly tag
things like figures and tables.
