We avoid using content::GpuDataManagerImpl::GetInstance() in ui
If we try to build chromium with shared component, this won't work. We
would need to add a gyp dependency on content_browser ui:compositor. But
that would result in a cyclic dependency. So, the only way is to have
ui:compositor not depend on content_browser, and therefore, not using
content::GpuDataManagerImpl
