1117 Support and implement additional configs through Fides.init()

[eastandwestwind]

Closes https://github.com/ethyca/fidesplus/issues/1117

Description Of Changes

Adds support for new config options, using Fides.init(), for exaxmple:

window.Fides.init({
    consent: {
      options: [{
         fidesEmbed: true,
         fidesDisableSaveApi: true,
         fidesString: "",
      }]
    },
});

Details:

1. Supports a fides_embed boolean config option. If this option is true, we "embed" the fides.js overlay UI (ie. “Layer 2”) into a web page instead of as a pop-up overlay, and never render the banner (ie. “Layer 1”). That page will be loaded in either the website or via a native app webview for managing privacy preferences instead of in a pop-up overlay. Use <div id="fides-embed-container"></div> as the parent DOM node for the embedded overlay.
2. Supports a fides_disable_save_api boolean config option. If this option is true, we should disable the save to API, but still trigger the FidesUpdated event and save preferences to the cookie.
3. Supports a fides_string config option. If it's set, fides_tc_string should supercede the cookie and any experience preferences, whether pre-fetched or client-side fetched. Importantly, if the fides_tc_string does not define a preference for a given consent item, but the experience defines it, then we set the preference for that item to use the default_preference from experience

Code Changes

• Adds all new config options to init()
• Implements all new config options according to the above acceptance criteria
• Write full-coverage e2e tests to test how user preferences take precedence from the cookie, experience (both client-side fetched and pre-fetched), and explicit fides_string

Steps to Confirm

• Run e2e tests to confirm: consent-banner-tcf.cy.ts and consent-banner.cy.ts

whew, nice work @eastandwestwind , lots of new features here! left some comments, but I don't think any of them are that big!

nice job @eastandwestwind !! I think it's looking good—I added a discussion question which might be worth thinking about, but it doesn't necessarily block this PR.

also, I think this PR also closes #4265 but can you confirm? if it does, go ahead and assign it to yourself :)
