Adding a new sandbox type for Windows' elevated privileges mode.

In order for Windows specific services that need to run with elevated
privileges, introducing a new sandbox type that can be used in the
service's manifest to make the service's process run without sandbox and
with elevated privileges. It's equivalent to no-sandbox on non Windows
platforms.
As part of that, removing the current API in UtilityprocessHost used to set
the extra privilege mode on top of the no sandbox setting.
