Break frontend into packages

[ravewebdev]

Similar to the new monorepo plugin setup, break the NextJS frontend into packages, such as the following:

• [ ] Core - next/auth, ACF custom settings (to be moved out of ACF at a later time per #635)
• [ ] Block Handler - include in core for 1.0.0, break out into separate package at a later time
• [ ] Algolia
• [ ] Gravity Forms
• [ ] ACF - custom blocks, fields
• [ ] SEO
• [x] LazyBlocks, CPTs - remove entirely
