Patch to provide csrss heap and fake win10 heaps

Follow up to bug 45646.
Starting with win10, the chromium sandbox tries to find a certain heap that's
shared with csrss.exe. It does this by enumerating all process heaps, looking
in the internal structure for the right flags. For that it assumes the internal
structure behind the opaque handle...
We need to do 2 things here.

1) Provide a csrss heap in the first place
2) Return handles that have a heap structure similar to win10 heap behind them
