Now that hardware tessellators chop, support raw triangles, and can
handle any path, we don't need complicated logic anymore to determine
when we can't use them. This CL simplifies the criteria for selecting
a tessellation algorithm and adds a fAlwaysPreferHardwareTessellation
context option to override it.

Previously we would completely disable hardware tessellation for a path
if there was any chance of a curve requiring more segments than
supported by the hardware. This CL updates the tessellators to simply
chop paths until they fit in patches, allowing us to finally draw any
path using hardware tessellation.

- most of the small diffs are because I moved GrWangsFormula.h out
of the tessellate/ directory and into the geometry/ directory since
it's more general than HW tessellation.
The previous implementation was based on the heuristic that the distance
from the true curve to the line segment would be divided by 4 every time
the curve was recursively subdivided. This was a reasonable
approximation if the curve had balanced curvature on both sides of the
split. However, in the case of the new GM's curve, the left half was
already very linear and the right half had much higher curves.
This lead to the approximation reporting fewer points than required.
Theoretically, those few points that weren't utilized by the left half
of the curve could have been made available to the right half, but the
implementation of that would be tricky.
Instead, it now uses Wang's formula to compute the number of points.
Since recursive subdivision leads to linearly spaced samples assuming it
can't stop early, this point count represents a valid upper bound on
what's needed. It also then ensures both left and right halves of a
curve have the point counts they might need w/o updating the
generation implementations. However, since the recursive point
generation exits once each section has reached the error tolerance, in
scenarios where the prior approximation was reasonable, we'll end up
using fewer points than reported by Wang's. Hopefully that means there
is negligible performance regression since we won't be increasing
vertex counts by that much (except where needed for correctness).

This started out as a sandbox to experiment with a Wang's formula
analog for rational quadratics, but it quickly became apparent that
running Wang's formula on the down-projected points was an upper bound
on what the rational version would have been (for both w<1 and w>1).
This CL therefore adds conic support by upgrading the tessellation
shaders to use ratoinal cubics, converting every path verb to a
rational cubic, and then running Wang's formula on the down-projected
points. In the future we can always drop in a better formula if we
work one out.
