Calling Python to find all these files is convenient, but error-prone. It's easy to forget to call GN again when adding a file. Each of these calls to Python also adds ~50ms to the run time of gn gen, which is small but adds up.
On my desktop, gn gen drops from 600ms to 150ms, noticeably faster.
This leaves one call to find.py for generating skia.h for fiddle. We're not quite sure how to automate that process to happen entirely inside the :skia.h action while maintaining correct dependencies, so I'm leaving it for now.

By default, MSVC generates standalone versions of all functions, including static inline functions that are only inlined. Those standalone versions are dead code. This /Zc:inline flag makes MSVC behave like all the other compilers, omitting those standalone functions. Chrome builds with this flag.
This CL cuts dm.exe and nanobench.exe each down by about 3MB, 19->16MB for DM and 15MB->12MB for nanobench. This shouldn't affect runtime speed, and didn't signficantly change clean build time on my Z840 (~90s either way).

This uses the win_toolchain's SetEnv.cmd script to set up the environment for x86 builds. Some of what it sets is redundant with what we set: include_dirs (INCLUDE), lib_dirs (LIB). I'd sort of like to learn what parts of it actually matter: VSINSTALLDIR? VCINSTALLDIR? likely PATH?
This will not work for local builds not using win_toolchain. I don't mind that too much, at least for now, maybe forever. Most humans should be using 64-bit builds.

The libc++ include paths have changed very slightly. I've left GN compatible with both older r12 NDKs and the new r13 to smooth the transition.
The libc++ in r13 depends on long-double math.h functions (cosl, atanl, etc.) only available in Android API v21 (Lollipop) and up. That's what the 64-bit bots were already on, so we just pull the 32-bit bots up to the same target. Conveniently, the oldest bots we have (N7 and N10) are on Lollipop.
The r13 MIPS64 sysroots are a little weird... /usr/include and /usr/lib64 but no /usr/lib. That'd be fine---we only want 64-bit builds---but Clang searches for /usr/lib64 via its path to /usr/lib, and without at least an empty /usr/lib, it can't find /usr/lib64. So you'll see a special mips64el section in the GN config where we do this all manually (other platforms pick this all up correctly from --sysroot). I've chosen to do this rather than fix it up in the asset create.py scripts so that we stay compatible with vanilla NDKs, which is convenient for developers.

The warning looks to helpfully pre-warn about possible link failures, but it's warning exclusively in places where we're doing things right.
The worst that happens ignoring this warning is a missing-symbol linker error.
I've taken the opportunity to batch in a few other de-escalations:
- Wconditional-uninitialized is done better by MSAN
- It'll take some work to dig Wformat-literal out of our shader compiler, but nothing looks unsafe
- Most of Wshift-sign-overflow is 0xff << 24. Don't want to ban that.
- Wdeprecated is mostly warning about features C++11 technically deprecated that might be removed in later releases. Punt!
- Wcovered-switch-default is pretty much the opposite of what we want.
- Wshadow is triggering too often to fix quickly. Probably mostly false positives.

is_skia_standalone.
