Add TCF v2.2 bridge mode for external CMP integration (v1.3.0)

Browse Source 
New cmp_mode setting toggles between the built-in banner (default,
unchanged) and a bridge mode that defers banner UX to an external
IAB TCF v2.2 certified CMP — e.g. Google's free Privacy & messaging
(Funding Choices) or Tarteaucitron.js — and listens to __tcfapi to
keep custom-script gating, attribution preservation, the att_cc_consent
cookie cache and the WP Consent API bridge in sync. Lets sites that
need a Google-certified CMP for EEA/UK AdSense/AdMob serving keep
using this plugin for everything except the consent UI itself.
