9bbff29d9c Add flatten and MakeFromBuffer to SkDescriptor
Create canonical flattening for SkDescriptor and unflattening
for SkAutoDescriptor.

Eventually Slug serialization and the remote glyphs cache will use
this method for SkDescriptor serialization.

26300d64ca Make allocation of SkDescriptor do initialization
The SkDescriptor fuzzer did not call init. This caused
mysterious failures.

Make SkDescriptor's constructor initialize its fields.
Remove init().

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.

73b0df10f7 tweak Descriptor_invalid_rec_size to not over-copy
When we pretend the SkScalerContextRec is 4 bytes bigger than it is, we
copy 4 bytes more than we should, and that's freaking out the ASAN bots.

Let's just say it's a little small.  Still wrong, no stack overflow.
