Remix PWA v5 Release Candidate

[ShafSpecs]

This PR aims to introduce the first release candidate (rc) of Remix PWA v5 - the next major version.

Includes a lot of breaking changes and packages.

@remix-pwa/dev

• Support added for Remix SPA mode. Now, the service worker is made aware of client route modules within routes. This leads to a modified behaviour regarding how workerLoader and workerAction works
• Ships a few new global variables (including a process.env object)
• Added support for single fetch use cases. workerLoader/Action behaviour has been modified extensively in this release and that includes being disabled in single fetch's case
• Removed all non-related exports from the dev package. Meaning WebManifest types are no longer exported from this package
• Deprecated option registerSW, this would be replaced by injectSWRegister, a boolean property, that would be shipped alongside a component to handle registration
• Automatically disables auto-injection of service worker registration if the worker is already being registered manually

@remix-pwa/worker-runtime

• Added runtime support for SPA mode - via the modified _route search parameter
• Disabled worker runtime APIs when single fetch is enabled in Remix

@remix-pwa/manifest

• 🎉 New package!
• Ships the ManifestLink component (removed from sw package)
• Now ships the WebAppManifest type - no need to import from dev anymore!
• Ships a new schema.json for JSON-format web manifests - get typings even within your json manifests!

@remix-pwa/sw

• New PWAScripts component: allows you to manually register your service worker with custom parameters including CSRF support
• Removed ManifestLink from the package
• New hook: installPWAGlobals that takes care of every setup required by Remix PWA within the client
• Removed useSWEffect hook - its main functionality has been ported to installPWAGlobals
• Removed the SkipWaitHandler, as well as sendSkipWaitingMessage utility
• Removed loadServiceWorker. Service worker registration now occurs via the vite plugin (automatically) or PWAScripts component (manually)
