Add Learn more about Product Settings note (https://github.com/woocommerce/woocommerce-admin/pull/4515)

* Add Learn more about Product Settings note

* Fix logic around new merchants vs existing, fix product count

* Refactor to use admin_init action, use WC_Product_Query

* Don't try to count products when recording added product date

* Rename function

* Completely drop recording product add times and just use oldest product date instead

* Remove onboarding update check, checking the profile is sufficient
