The old win_toolchain script required a Chromium checkout, and
extracted portions of the win_toolchain from that to build the
Skia asset. Instead, use the depot_tools script that assembles
a toolchain from a locally installed MSVC.
The create script doesn't do that, but relies on the user to
run that script first. Automating everything would be a nice
follow-up.
With the new strategy, the toolchain directory is simpler, and
no longer contains the depot_tools kruft or extra directories.
Adjust the bot scripts accordingly. (Renaming the directory to
win_toolchain from 't' would be a nice touch, too).
Finally, I built the new toolchain with the updated process,
and included the ARM64 compiler and libraries, so we can set
up a bot to build Windows ARM64.

'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.

Recent versions of ANGLE require this. See:

This also updates us to the latest version of the Windows SDK,
2015 Update 3 (Windows 10 SDK).
