These flags let symbols cross-link from anything in the group.
This becomes useful if we try to make more parts of Skia
components, letting binaries link .a static libraries that
depend on each other without worrying about the order they're
specified on the link line / in the .rsp file.
Few of our bots should be affected by this, as lld doesn't
really need this workaround.

Chrome stopped using them in January:
https://chromium-review.googlesource.com/c/chromium/src/+/832593
For them, it significantly accelerated goma builds. From my tests,
I think we'll see some small speedup. Note that our older build
system invoked through CMD, which limited us to 8k of command line.
GN/ninja don't do that, so we have the full 32k limit. However,
we do use CMD to do our 32-bit builds... But that doesn't matter,
becase AFAICT the longest command line we generate right now is
only about 2.5k long.
Note that (like Chromium) this continues to use rsp files to link.
Those command lines *can* become ridiculously long.
The original motivation, and a nice benefit of this change:
It makes the output of ninja's compdb tool much more useful.
That tool emits JSON in a standard format describing the commands
used to build each source file. Other tools (eg Visual Studio Code)
can parse that JSON, and deduce the correct defines and include
paths to help with symbol navigation.

We expect .BAT and .EXE to be on PATHEXT. Also, although Python
CreateProcess doesn't honor PATHEXT, it will try .EXE. This allows most
commands to be platform-independent, and also resolves the issue with
the cpython package not including python.bat.

'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.

To make this simpler in the future, add a python script that finds the
most recent 2017 toolchain, and use that. If/when we update the bot
toolchain, this will be even more helpful, because the Chromium toolchain
isn't perfectly in sync with the general update channel, so people are
likely to have a newer/older release locally.
Note that explicitly setting win_toolchain_version in your GN args
suppresses the python script, so you can choose to build with whatever
version you need.

This reverts commit c070939fd1.
Reason for revert:
This has some knock-on effects in the generation of Android.bp from our GN files. See gn/gn_to_bp.py? We're seeing things like "tmp/tmpsBVycx/gen/" end up in the include search path in Android.bp, which obviously don't exist there...
