Site Storage Controls: Remove /siteData and redirect to /content/all

CL removes the entry point into chrome://settings/siteData and redirects
it to chrome://settings/content/all. Also adds a redirect to the Chrome
client to redirect navigations to the deprecated /siteData page to the
/content/all page.

All user facing changes are behind the kConsolidatedSiteStorageControls
feature.
