Use depot_tools toolchain, remove now unneeded code, fix not including path to win sdk tools

This is enough for this to work OK:

[gn-2013]d:\src\cr\src>gn gen out_gn
[gn-2013]d:\src\cr\src>ninja -C out_gn gn
[gn-2013]d:\src\cr\src>out_gn\gn gen out_gn2
[gn-2013]d:\src\cr\src>ninja -C out_gn2 gn
...
[297/297] LINK gn.exe

I'm not sure if we need all the deleted stuff for something
else, but I guess we can revive it when we need it.

(There's some dependency problem with linking atm, as
"ninja -C out_gn gn" always relinks, but I think it's unrelated.)
