Remove references to apigen from configuration files

Commit d6bd828 removed apigen from
WooCommerce core repository as we are moving it to its own repository (https://github.com/woocommerce/woocommerce-api-docs). This
commit removes the apigen from configuration files. In most cases, it is
just removing the apigen directory from the exclude list of things like
PHPCS and Code Climate.
