Get gn_all/gyp_remaining working for Windows.

Get gn_all/gyp_remaining working for Windows.

This change doesn't actually cause anything new to be built, but it makes 'gn_all' and 'gyp_remaining' exist as targets on a windows build, and explicitly lists all of the targets built on win that weren't listed before.

A number of these targets should actually build in a GN build, but I will take care of that in a follow-up CL.

A revert of this CL (patchset #2 id:20001) has been created in
https://codereview.chromium.org/1071603005/ by dpranke@chromium.org.

The reason for reverting is: Seems to have broken the Win x64 debug builder:
