builder/remotecontext: deprecate CachableSource, NewCachableSource

Browse source 
This type (as well as TarsumBackup), was used for the experimental --stream
support for the classic builder. This feature was removed in commit
6ca3ec88ae, which also removed uses of
the CachableSource type.

As far as I could find, there's no external consumers of these types,
but let's deprecated it, to give potential users a heads-up that it
will be removed.
