Ensure void type is resolved when running without image

To initialize java.lang.Void correctly, we need to ensure the 'void'
class is initialized in the dex cache of core-libart (because Java
code relies on it). However, if we run without image, the dex cache
may not contain the void class before we initialize java.lang.Void
class.

This CL fixes this by forcing the resolution of 'void' class when
initializing the runtime without image.

We also generalize that to other types by not skipping verification
when running with preopted oat files without image. By verifying
all classes, we ensure all resolved types are in the dex caches.
