Implements the non-deprecated builder.

Any class inheriting `BrowserContextKeyedServiceFactory` should
implements either `BuildServiceInstanceForBrowserContext` or
`BuildServiceInstanceFor`. The second one being deprecated,
this CL
replaces it by the first one.

This also ensures that, instead of applying `WrapUnique` to a `new` raw
ptr, it directly uses `make_unique`.
