Move StoragePartition into content/public and remove BrowserContext::GetDOMStorageContext().

Eventually all the storage context accessors will be removed from BrowserContext. Instead, users should retrieve the storage context from the StoragePartition.

This also changes RenderProcessHost to take in a StoragePartition removing the need for a re-lookup its storage contexts.
