Resubmit of 'Allow loading of host runtime for Windows"

This makes the loading of host runtime dependent on a Java system
property instead of simply ignoring it for Windows. By default, this
will be loaded (keeping the current behaviour working for non windows platforms).

But setting use_base_native_hostruntime to false will allow the host runtime to be
skipped when libandroid_runtime is loaded.
