Change default Win10 SDK from 10240 to 10586

Change default Win10 SDK from 10240 to 10586

When Chromium switched to the Windows 10 SDK it specified the 10240
version but this is missing IVirtualDesktopManager and other types. This
doesn't affect VS 2015 builds because the package the 10586 SDK, but it
does affect builds where DEPOT_TOOLS_WIN_TOOLCHAIN=0 is set.

This change updates the local-toolchain builds to require the 10586 SDK.
Developers are responsible for installing it.

Can you take a look? It looks like an oversight that this wasn't updated earlier
since IVirtualDesktopManager seems to only exist in the 10586 SDK. The VS 2013
and 2015 packages both use the 10586 SDK so clearly the local-SDK builds should
use it as well.

In testing I hit an odd link error with this change:
    LINK : fatal error LNK1104: cannot open file 'metro_driver.dll.lib'
but I think that is spurious and unrelated. I'm doing a pull/rebuild now.

There are three external projects (angle, ffmpeg, gyp) that references the 10240
SDK but I don't think it matters whether they are updated. I think they can be
updated as/when needed.

lgtm. I just removed metro_driver elsewhere.
