39b978241b Update code to prepare for -Wformat-nonliteral.
-Wformat-nonliteral does not work with variadic templates, and requires
a constant format string.

These changes uncovered one incorrect format string (%u -> %lu for a
DWORD in dm.cpp)

9cb74e9079 [bazel] Compile gms for wasm and WebGL
PS 1 is re-generating existing BUILD.bazel files
PS 2 is generating BUILD.bazel files for tests/gms
PS 3+ makes modifications to build all of the gms and tests.

It is recommended to view this CL with just a diff between
PS 2 and the end, due to the large amount of generated changes
in PS 1 and 2.

We make a filegroup for the gms and tests because they need
to be compiled as one large blob in order for the registries
to work. Maybe in the future we will break these up, but at least
for WASM/JS, the overhead of starting a browser for each new
test would likely grind things to a halt, so we just group them
all together for now. It's also the most similar to what we
currently do.

In gm/BUILD.bazel and tests/BUILD.bazel, we add a cc_library
that encapsulates all of the deps of the tests, so we can
easily include that the build. These were discovered via
trial and error, not anything automatic or systematic.

The is_skia_dev_build config_setting is very similar to the
GN equivalent from which it was based.

The list of gms and tests to skip (e.g. which are incompatible
with WASM) was determined by building the wasm bundle:

modules/canvaskit$ make bazel_gms_release
tools/run-wasm-gm-tests$ make run_local_debug
# Don't forget to click the button on the screen after the
# browser loads

This way of invoking the tests will be replace soon with
`bazel test <something>`. As such, I didn't bother fully
documenting the current way.

Suggested review order:
 - modules/canvaskit/BUILD.bazel taking note that we always
   use profiling-funcs to make the stacktraces human readable.
 - gm/BUILD.bazel and tests/BUILD.bazel to see the lists of
   gms/tests. Notice the tests are roughly partitioned because
   we don't support things like vulkan/PDF in the wasm build
   and we will want a way to not build certain tests for
   certain configurations
 - tools/* noting some of the cc_libraries added to make
   dependencies easier to add when needed.
 - All other files.

87aa7a9095 Add SK_PRINTF_LIKE to existing variadic print functions.
This shook out a handful of formatting issues:
[SkVMVisualizer]
- We were passing plain text like "width:35%;" through printf.
- One particular opcode type was printing a string as a number.
[Skottie, SortToy]
- Used wrong integer type instead of %zu for size_t

This CL does not update print functions which take printf arguments via
variadic template, as __attribute__((format)) does not support this
style. These could be converted to va_list style, but that's not done in
this CL.

(For some reason, GCC requires the attribute to be set on a prototype
for freestanding functions, so a few of these now have a prototype
immediately followed by a declaration.)

4250effcc5 Prepare to reenable unreachable-code warnings.
Adding double-parens around an `if ((false))` squelches the warning.
In other cases, you can squelch the warning by assigning the
always-constant(-on-this-machine) check into a constexpr bool.

3695bdb587 Refactor SkMatrixProvider slightly
There was only one virtual method, so switch that to a bool stored in
the base class. The derived types exist as hints for the reader, and an
easy way to adjust how the new localToDevice is constructed.

With this change, we don't need SkSimpleMatrixProvider. SkMatrixProvider
is concrete, so we can use it directly. SkOverrideDeviceMatrixProvider
no longer needs the original provider for anything, so remove that
parameter. It now exists solely to inhibit the hitsPixelCenters flag.

Fix a few spots (SkParticleBinding, some sites in SkRuntimeEffect) where
we used SkSimpleMatrixProvider, even though the local coordinates being
passed did not obey the hits-pixel-centers constraints.

Most importantly, document how localToDeviceHitsPixelCenters works.

8c3d183cc2 Rename SkSL 'srgb_unpremul' to just 'color'
Added comments to explain the semantics (both what's expected when you
set the uniform, and what you see in the shader). The old name was
confusing, because it sounded like you got an sRGB color in the shader.
This is terse, but I think it's the cleanest syntax - and for embedding
clients, they can use C++ (etc.) API to require that color uniforms are
assigned from color types.

668995122f Fix when a glyph has a path
Always call generateMetrics before generatePath so that generateMetrics
can determine which glyph representation to use and if that glyph
representation can be modeled as a path.

Pass an allocator into generateMetrics so that it can set the path to
not existing. This allows generatePath to continue to work as it used
to, creating a path if any path is available. However, generateMetrics
may first set the path to not existing.

Update getPath and internalGetPath to use the path on the glyph if it
has already been set. Update makeGlyph and internalMakeGlyph to always
call generateMetrics first (which is now more like initGlyph).

Update the SkGlyph::PathData to indicate that it is a dev-path and not a
user-path. A user-path will have effects applied to it. A dev-path is
always a resolved path which is always filled -- unless it is hairline.

Update everything else for the knock on effects and to take advantage of
this information.

20c6a947af Add SkImage::makeRawShader
This creates SkImageShader instances that do not perform color space
conversion, nor do they premultiply their pixels (if they started out
unpremultiplied). These are useful for runtime shaders that want
non-color inputs (like normal maps or lookup tables).

Includes GM that demonstrates lack of color conversion, and lack of
premultiplication in the context of a lighting shader.

672062da97 generate fully transformed device bounds for clipping
The direct mask sub runs were only shifting the device bounds,
and never really transforming them. This adds code to do the full
bounds transform when the positionMatrix does not represent an
integer offset.

Add a meaningful clip to the slug GM to demonstrate change. With
the old code, the slugs did not respect the clip. Now they do.

25c0e1a8dd GrSlug prototype
A GrSlug encapsulates an SkTextBlob at a certain origin, using a
given paint. Once a blob is converted to a slug, it can be drawn
through a canvas and will obey the canvas's mapping and clipping.

The glyphs encoded as mask will be transformed using bi-linear
interpolation. The other glyphs type will draw as they normally
would. This allows drawing an SkTextBlob using the original
glyph data from the cache.
