PASE-1974: pmc-larva should support cookie consent category

[shawncook]

Per PASE-1974, we need to check for OneTrust cookie consent before setting cookie using pmc.cookie.set(). This passes in a category of 'functional' for the webfont loaded cookie setting.

I thought we handled this in WP, when the loader script is enqueued. Is that not the case?

[shawncook]

@ethitter we do, in that pmc cookies aren't set when a user rejects all cookie categories. However, this lets us pass in a category when calling pmc.cookie.set() to conditionally set individual cookies based on whether the user has consented that particular category.

You're right though - there is a lot of existing code related to this behavior:
https://github.com/penske-media-corp/pmc-plugins/blob/main/pmc-first-party-cookie/src/js/classes/FpcConsent.ts
https://github.com/penske-media-corp/pmc-plugins/blob/main/pmc-cxense/assets/src/pmc-cxense-consent.js

We don't really need this, since fonts_loaded is covered under defaults in pmc-consent.js
