Add runtime search paths to Instance descriptor

So that Chrome can configure Dawn to load SwiftShader from
the bundled/module directory. The shared libraries and ICD
are packaged in a separate directory while dawn::native is
linked statically into the Chrome executable.

Change the Vulkan backend to use these paths for loading
Vulkan.
