fix(testing): reintroduce and deprecate setBaseTestProviders (#9905)

This change reverts the removal of setBaseTestProviders that was
introduced in 8d746e3f67.

Instead, setBaseTestProviders and the providers provided from
`@angular/platform-browser-dynamic/testing` and `@angular/server/testing`
will still work for the next release, but are deprecated.

See 8d746e3f67 for how to upgrade.
