Make stencils be attachable to render targets created via SkSurface::MakeFromBackendTextureAsRenderTarget

This is a regression from "Refactor to separate backend object lifecycle
and GpuResource budget decision".

GrGLRenderTarget::CreateWrapped creates only render targets that wrap
the FBO.
GrGLRenderTargetTexture::CreateWrapped creates render targets that
wrap the texture.

Use the latter as the implementation for
SkSurface::MakeFromBackendTextureAsRenderTarget.

The test contains disabled code. The
MakeFromBackendTextureAsRenderTarget does not copy the existing texture
contents to the FBO render buffer.

Adjust tolerance to fix bezier glitches issue

In a previous CL: https://codereview.chromium.org/1126793003, the value
of gDegenerateToLineTol was changed from 1.0 to 0.25 which caused the
bezier glitches.

This CL changes the value to SK_ScalarRoot2Over2, with this change the
bezier curve looks fine, and the result of the layout tests pointed out
in this bug: https://bugs.chromium.org/p/chromium/issues/detail?id=472847
is also reasonable.

Delete unused code from SkColorSpace

IMO, a lot of this code reflects an oversimplified view of
handling color profiles.  And a lot of this code is valid
math/checks/enums that we will eventually need.

Right now, it's all unused and is adding a bit of clutter

it makes sense to start simpler and build this back up as

pathops: Split loop type cubics only when there is a self-intersection.

The ComplexBreak code comes from Loop and Blinn, which requires loops to be
split if either double point is visible.  However for intersection loops only
need to be split when there is actually a self-intersection (when both double
points are in [0, 1]).  This patch splits cubics much less often so the output
doesn't have extra segments unless the input had a self-intersecting loop.

pathops: Cosmetic only change, update comments around ComplexBreak().

Rename loopT to splitT and make it clearer that it is not just
self intersecting loop cubics that are split.

Review URL: https://codereview.chromium.org/1914873002

Update SK_IMAGE_VERSION, run nanobench on its own image set

I've added a new directory to the cloud
(gs://chromium-skia-gm/skimage/v4/nanobench) which will
allow us to run dm and nanobench on different sets of
images.

The dm image set will stay the same, and includes
incomplete images, edge cases images, etc.

The nanobench set is much smaller, and includes jpegs and
pngs that we've found useful to bench in the past, plus
a couple of each for the other formats.  We can refine
this set as we move forward (and may also want to monitor
these images on perf.skia.org).

For now the goal is to reduce nanobench runtime by not
testing on many, many obscure images that are not
particularly interesting to time.

The actual change to use nanobench images is in:

Batch multiple single NVPR draw paths to instanced draws

Batch multiple single NVPR draw paths to instanced draws.
A draw path batch can be combined to other batch if the
batches do not overlap and have same draw characteristics.

Join the batches in linked list and flatten the list to a
path list during draw time.

Replace GrPathRendering::drawPath with GrPathRendering::drawPaths.

Perf changes ARM, Shield TV device, Tegra X1 GPU:
                desk_chalkboard.skp_1 21.5ms -> 17.8ms 0.83x
                    desk_mapsvg.skp_1 7.49ms -> 6.18ms 0.82x
Others results are more volatile.
