Remove Value/renderValue public API from "flipper"

Summary:
Moving Value/renderValue API to "database" plugin as these APIs used exclusively by this plugin.

Alternative to that could be moving this API to "flipper-plugin" instead, but I think it doesn't make sense to expose public API which is only used in one plugin.
