Manually add services that set cookies

[ricardobrg]

Although our cookies scanner can miss external additions, such as those made with an iframe, users can manually set the services that set cookies in the TIKI WooCommerce plugins' settings.

This can be done by identifying the tag that sets the cookie with a specific data attribute that will be used to remove it before the browser loads it. This way any missing services that set cookies and were not identified by the scanners can also be added to the cookies categorization UI for easy categorization.

Tasks

• [ ] Define the function to remove/invalidate the whole tag based on the data attribute.
• [ ] Add UI section to add Services and its backend functions
