Refactor: remove ClassicEditor from window.givewp.form.components and use the new @givewp/form-builder-library npm package

[glaubersilva]

Resolves GIVE-140

Description

The ClassicEditor was previously mounted in the window global object to prevent code duplication in the addons.

But it also introduces a few problems like forcing bumping the minimum Give core version in the addons, and other problems related to possible changes of the components in the core that can break functionalities in the addons.

In the future, a JS package will be released to share the components between the addon without major issues

But for now, was decided to remove this component from the global window object and fork it in each addon that needs to use it.

So, this PR removes this component from the global window object and also replaces some components with the ones shipped with the @givewp/form-builder-library npm package.

This PR also changes the OptionsPanel component used in the donations levels and name title prefixes to the version shipped with the new package.

Affects

• The window.givewp.form.components property.
• Email message content in the email settings of V3 forms.
• The Agreement Text content in the Terms & Consent block of V3 forms.
• The Donation Instructions in the Offline Donations Gateway.
• Donation levels in the Donation Amount and Levels block.
• Name title prefixes in the Donor Name block.

Testing Instructions

1. Create or edit a v3 form;
2. Go to the email settings and play around with the email message content of the email notifications.
3. Add a Terms & Consent block, go to the Agreement Text content, and play around with the editor options.
4. Go to the Offline Donations gateway settings and play around with the donation instructions content of the gateway.
5. Go to the donation levels in the Donation Amount and Levels block and play around with the options/levels.
6. Go to the name title prefixes in the Donor Name block and play around with the options/prefixes.

@glaubersilva is any currently released add-on using this component? technically this was released in the latest version of GiveWP so we need to be extra careful about removing it.

[glaubersilva]

@jonwaldstein Only the FFM and Tributes addon was using it, but the PRs that implemented it still weren't released, so we are safe.

The other addon that uses a component with the same name is the PDF Receipts, but it also uses its own version of this component.

You can double-check it here: https://github.com/search?q=org%3Aimpress-org%20ClassicEditor&type=code

[jonwaldstein]

@glaubersilva just to be safe, let's hold off merging this until the add-ons are not referencing this component through the window on their develop branches.

@jonwaldstein This is ready for re-review.
