Assuming this survives, we can probably simplify other code in SkPath
(e.g. Iterators) that today worry about consing up moves after close.

This shows SkPathBuilder::snapshot() can return more memory-efficient

- 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

In theory, a convex shape is still convex if transformed by an affine
matrix. However, SkPath segments are specified using floats, and attributes
like collinearity can break under some transforms due to finite precision.
Computing convexity is non-trivial, so there is value in SkPath caching this
calculation. Convexity is useful, as both the CPU and GPU backends can draw
convex shapes faster than non-convex.
To balance these two (fragile float math and value of caching convexity),
this CL invalidates this cached state if the transform could change convexity.
In the general case, it is assumed that convexity could change. Special cases
where it is safe to keep the cached state after transform are:
- identity transform
- scale/translate transform if the path is known to be axis-aligned
All other combinations invalidate the cached state, forcing it to be
recomputed.
"axis-aligned" means the segments in the path are all axis-aligned, horizontal
or vertical (e.g. a rect or rrect)

That GM has a path with 16k points, arranged in a rectangle. When we try
to draw it in Ganesh, we first check to see if it's a (closed) rectangle.
We eventually decide that it is a rectangle, but not closed, so it gets
passed along. Then we construct a GrShape, which tries to simplify the
shape, again asking if it's a rectangle...
Each isRect query was iterating over the 16k verbs, and for each one,
calling atVerb(i). That, internally, calls verbs(), which calls validate()
in debug builds. So we were walking all 16k points 16k times (to ensure
the bounds were correct). The end result is that the GM took over 11
seconds to draw, and now takes 3 ms.
