Move Standard profile's setup to config

[NormPlum]

The Standard install profile does a bunch of setup tasks. Creating content types, fields, permissions, roles, views, etc. Most of these are code in standard_install(), but some are config in /core/profiles/standard/config/*.json.

I think it might be good to move everything to config. Some things like creating views can't really be done in code as there's just too much of it. Some things can't be done in config either (like adding content since it lives in the database). But I think config is easier for people to add and update since they can make the changes in the UI and then copy the config files over.
