GN: _turbo -> -turbo to match Fuchsia

We might as well match the folks who are using our GN files now.

We've got plenty of strategies in our pocket for when we try to move Chrome
onto our GN files (and who knows, there may be even a new better way by then):
  * Same sort of rename in Chrome's third_party
  * Aliased targets via //build/secondary in Chrome.
  * Indirection via build_overrides

https://codereview.chromium.org/2259493002/ could leave
a MonotonePoly with zero edges. This is a problem for
Poly::addEdge(), which assumes that MonotonePolys always have
at least one edge. The fix is to move the check and early-out up to
Poly::addEdge(). This should also tighten up the vertex count.

(Unfortunately, the only repro I have for this issue is very
convoluted, and requires non-landed code.)

Fix assert caused by floating point error in tessellating path renderer.

In rare cases, floating point error causes the tesselator to add the
same Vertex to more than one Poly on the same side. This was not a big
problem when we were allocating new vertices when constructing Polys,
but after https://codereview.chromium.org/2029243002 it causes more serious
issues, since each Edge can only belong to two Polys, and violating this
condition messes up the linked list of Edges used for left & right Polys
and the associated estimated vertex count.

The fix is to simply let the first Poly win, and skip that vertex for
subsequent Polys. Since this only occurs in cases where vertices are very
close to each other, it should have little visual effect.

This is also exercised by Nebraska-StateSeal.svg.

Add test for platform encoders, turn off platform encoders by default

Clients that like WIC and CG can still use them.  And we can be
confident about that, since we now test WIC and CG.

Let Skia always use our own encoders by default, so we can do cool,
custom things on all platforms.

Only test SVG DM sources against direct raster/gpu sinks.

There isn't much value in testing against indirect or vector sinks.

Remove SkPreprocessorSeq.h and SkTypedEnum.h.

These were added to allow the use of typed enums before typed enums were
available on all platforms. Now that typed enums are available, just use
them directly.
