'windk' is no longer a thing. There are two separate variables to point
at your compiler (win_vc), and SDK (win_sdk).
'msvc' is no longer a thing, either. By default, we look for 2017 and
then 2015 (in the default locations). If neither is located, use an
assert to let users know they should set win_vc. Then, detect if win_vc
points at a 2017 or 2015 installation, and configure it automatically.
Because the toolchain is now 2017, update the GN files to handle building
x86 in that configuration. In fact, we only support x86 builds (with 2017
or 2015) using the toolchain assets. Keep a 2015 toolchain around as a
new asset, so we can add bot coverage.

Bug: b/70203010
From https://github.com/libjpeg-turbo/libjpeg-turbo/commit/c308d434.
This commit fixes a bug in BitmapRegionDecoder, and is the tip of tree.
Rather than using our mirror, just pull in upstream directly. Move our
config files into third_party/libjpeg-turbo, so we can just DEPS to
upstream. These files are unchanged, except jconfig.h, where I added a
comment regarding arithmetic coding.
Add a test image which demonstrates the bug.

The old code made the wrong assumptions about premultiplication.
There are three relevant steps here for decoding a webp frame:
1 tell libwebp to decode
2 colorXform the result (sometimes)
3 blend with the prior frame (sometimes)
Rearrange the code to premultiply at the blend step, in a linear space.
If the client wants unpremul, the blend step will unpremul after.
If there is no blending, the colorXform (if any) will premultiply.
If only step 1 is necessary, let libwebp premultiply.
This fixes an animated image that has an opaque frame 0 followed by a
frame with alpha that blends with it.
Add the test image that failed (https://mathiasbynens.be/demo/animated-webp)
The prior fix is in 42bae8faa4. It did
not properly handle the colorXform when there was no blending step.

Bug: b/65290323
If a webp file is truncated such that no rows can be decoded,
WebPIDecGetRGB does not initialize its "last_y" parameter. We use
rowsDecoded (passed as last_y) to determine which remaining rows to
fill.
Check the return value of WebPIDecGetRGB. If it fails (returns null),
or rowsDecoded is <= 0 (matching Chromium's check), return
kInvalidInput, since there is nothing to draw.
Note that this is a change in behavior for Android. Previously we
would decode an empty webp to just a transparent/black rectangle,
whereas now we simply fail. I think this is a change for the better.
Add a test which truncates a file to have 0 rows available and attempts
to decode it. msan verifies that we no longer depend on the
uninitialized value.
Stop attempting to test decoding subsets from an incomplete webp (in
CodecTest.cpp). Unless we have decoded the portion covered by the
subset, this will fail.
Remove test images inc0.webp (from both dm/ and colorspace/) and
inc1.webp. These just decode to transparent rectangles. Replace them
with inc2.webp and inc3.webp, which decode part of the image and then
have to fill with transparent.

Fix core.gni to use not use Assembler for none cpu.
Right now, there are no outputs because we aren't compiling
dm or nanobench. However, this still compiles the skia
library and creates two executables, so it's a good canary
for a real WASM build.
Additional note: the two executables in question don't draw
anything to the screen via GL, which is still not possible with
Skia+WASM.
