Reason for revert: Task Test-Debian10-Clang-NUC7i5BNK-GPU-IntelIris640-x86_64-Release-All-DDL3_TSAN has been failing since this CL landed.

1f8c31b101 [infra] Add initial Bazel rules and files
These rules can be used to build our GMs on WASM+WebGL and
libskia.a with just the CPU backend (and most other features
turned off).

This can be done with the following commands:
  - bazel build //modules/canvaskit:gm-bindings-wasm --gpu_backend=gl_backend --with_gl_standard=webgl_standard
  - bazel build :skia-core --config clang

This pivots slightly from http://review.skia.org/463517
by using config_settings [1] instead of platforms for
the optional features that we control. This pivot was
suggested in [2]

We have BUILD.bazel files in many of the subdirectories
that specify filegroups for the appropriate files. In
an effort to make //BUILD.bazel more readable, it is
the responsibility of these subfolders to deal with
conditionally including certain .h or .cpp files.
This is done using select statements and config_settings
or platform constraints as necessary.

For example, src/gpu/BUILD.bazel will different private
filegroups for each of the supported gpu backends [3]
and a more-visible filegroup called "srcs" that has
the right selection of the private files to be used
for compilation.

An effort has been made to avoid using glob() in our
BUILD.bazel files. These file lists were made by using
`ls -1` and some regex to add in quotes. We might want
to make a helper script to assist with that, if necessary.

To specify which options we have, the settings in
//bazel/common_config_settings/BUILD.bazel have been
redesigned. They make use of a macro `string_flag_with_values`
that removes the boilerplate. Patchset 36 shows what the
file looks like w/o the macro.

The top level BUILD.bazel file will still need to use
some logic to handle defines, because local_defines is
a list of strings, not a list of labels [4].

Suggested Review Order:
  - WORKSPACE.bazel to see the new dependencies on the
    emsdk toolchain and bazel_skylib
  - bazel/common_config_settings/* to see the few settings
    defined (we have more to define, see BUILD.gn and
    //gn/skia.gni for ideas)
  - BUILD.bazel to see the "skia-core" cc_library rule.
    See also "gms" and "tests"
  - modules/canvaskit/BUILD.bazel to see the use of
    the emscripten "wasm_cc_binary" rule, which depends
    on the "skia-core", "gms", and "tests" rule. Note that
    it only builds some of the gms as a proof of concept.
  - The other BUILD.bazel files. Some of these are not
    platform or feature dependent (e.g. pathops). Others
    are (e.g. gpu).
  - All other files.

6c8e2e832e Fix winding when splitting edges at out-of-bounds vertices
Add GM repros and up triangulation verb count to match chromium's define
The GMs draw incorrectly in (base->p2) with the updated verb count, but
would draw fine w/o the increased verb count because a different path
renderer would be chosen.

This fixes a latent bug that was in the edge splitting code of the
triangulator that was exposed by https://skia-review.googlesource.com/c/skia/+/432196
Before that CL, intersections of two lines would be clamped to one of the
4 vertices of the 2 segments. In the CL linked, the clamping was adjusted
to clamp X and Y axes separately, so it increased the chance that a
clamped intersection would have its X or Y coord equal to line's vertex
but differ along the other coord (when they both equaled, they were
considered coincident and splitting that edge did nothing).

Splitting an edge at its intersection was intended to split (p0 to p1)
into new lines (p0 to v) and (v to p1) where p0 < v < p1 according to the
vertical or horizontal sorting that was imposed on the mesh. For a given
line segment and a clamped vertex, there are 8 ways the intersection
could be clamped (4 edges and 4 corners). If the edge has a positive
non-zero slope, a zero slope, or an infinite slope, in all cases the
clamped intersection will be sorted correctly and satisfy p0 < v < p1.

However, if the edge has negative slope
  vertical: p0.y<p1.y and p0.x>p1.x,
  horizontal: p0.x<p1.x and p0.y<p1.y
then intersections snapped to the primary sorting axis will be out of
order and produce a split such that v < p0 < p1 or p0 < p1 < v. This
was already detected, but it didn't update the winding of the new edge
to preserve the original winding from p0 to p1.

In these out-of-order cases, the intersection point is the top of both
the new and old edge, or the bottom of both the new and old edge. This
means that winding "top to bottom" on the new edge would go in the
opposite direction as the original winding from p0 to p1. Flipping the
winding on the new edge preserves the intended winding of the contour
while still allowing the edges/vertices to be sorted consistently.

This showed up as large gradients in the AA triangulator because w/o the
winding adjustment, the winding flip at the new edge would confuse the
border extractor that was used to compute insets and outsets for the 1px
coverage ramp. It would then use edges that were normally unrelated to
each and declare their line intersections as the "interior" with full
coverage. Obviously these could be anywhere so the 1px coverage ramp
would get smeared across that shape.

9fa47cc1c6 Make class members that are static constexpr also be inline.
This is in prep for compiling with -std=c++14 and -Wno-c++17-extensions
when building with clang. Chrome has encountered problems with
third_party headers that are included both in Skia and other Chrome
sources that produce different code based on whether preprocessor macros
indicate a C++14 or C++17 compilation.

In C++17 they are already inline implicitly. When compiling with C++14
we can get linker errors unless they're explicitly inlined or defined
outside the class. With -Wno-c++17-extensions we can explicitly inline
them in the C++14 build because the warning that would be generated
about using a C++17 language extension is suppressed.

We cannot do this in public headers because we support compiling with
C++14 without suppressing the C++17 language extension warnings.

397fdfdf18 Implement separate crop filter
Right now the crop image filter is hidden in src/ and is only used in
a new GM to test out its functionality. In later CLs the plan will be to
migrate individual filter effects away from the built-in crop rect to
composing themselves with this image filter.

Eventually, the crop filter will be made public as part of the
SkImageFilters factories so there can be independent control on input
and output cropping. Its features will also be expanded to support more
tile modes than just kDecal.

Once all other effects rely on this crop filter, the legacy system can
be deleted and the effects can be more easily updated to the rest of the
new image filter API. This crop filter is actually the first image
filter to be implemented only in terms of the new API (and skif coord
space types). This highlighted a few pain points that still exist in
terms of the API, where I have added comments to capture how they could
be improved. Unfortunately, they aren't addressable until the rest of
the implementations have been migrated.

144926d968 Allow subpixel nested rects to have nearly equal x/y half widths
When transforming to device space, equal local-space half widths in X
and Y might end up being fractionally different, which would prevent
optimizing the nested rect path to use the stroke aa rect op. Visually,
these very small differences are not going to be noticeable and the op
can just arbitrarily pick one of the two widths to use for coverage.

Also fixed an issue where if the aa stroke op returned null from
MakeNested(), drawSimplifiedShape() assumed it meant nothing needed to
be drawn. After https://skia-review.googlesource.com/c/skia/+/427976,
this actually isn't the case and it should attempt path rendering for
the unbalanced subpixel nested rects.

In the linked bug's case, the square rects would not transform to
identical x and y half widths depending on the UI scale of the browser
(differing by a negligible amount). This would then return a null op
and skip falling back to the path renderer so nothing would draw.
