Use Vite as our build service

[padarom]

This PR migrates away from Nuxt and directly to a Vite-powered Vue service. There's multiple additional improvements under the hood:

@awtrix/dev

We got rid of the @awtrix/dev package in order to provide a centralized awtrix binary, rather than also adding awtrix-dev. The awtrix binary now includes commands to pack, init and run custom apps.

This however means that we have to move dev dependencies to regular dependencies as they are necessary for building custom apps. This increases bundle size and install time for non-developers, that just want to run awtrix start, but I think this is worth it for a more streamlined development experience; especially given that you only really have to install Awtrix once on your Raspberry, so an additional minute and maybe 50MB shouldn't matter too much.

Switch from Oclif to yargs

Oclif comes with a lot of overhead as it does its own parsing of the project structure to determine command availability. This has annoyed me multiple times so far, as the entirety of its error handling is silent and I constantly had to debug why a command was suddenly not available anymore. Also, this seems to have made constant trouble with TS/JS interoperability.

yargs is a bit more verbose to use and doesn't come with as great typing as Oclif, but works just as well for our purposes.

Nuxt -> Vite

A switch from Nuxt was necessary for using Vite, since Vite only supports Vue 3, while Nuxt doesn't yet. Since we essentially only have a single page (ignoring a desktop configuration option) we don't get much benefit from using Nuxt anyways, therefore this is also removing a bit of complexity. It does mean however that have more power over how exactly our Vue app is initialized.

The switch to Vite also allows us to use the Typescript-compatible Vite features programatically, such as spawning a development server, building awtrix itself for production, or building only a specific Awtrix HD app (potentially also with HMR functionality).

esbuild

I'm also migrating from tsc to esbuild, which drastically improves Typescript build time. It's what Vite uses under the hood and one of the main reasons it's so much faster than a Nuxt compile.

A caveat is that esbuild simply transpiles and doesn't perform any type checking, so we still have to run tsc --noEmit in parallel to provide type safety, while using esbuild to generate a JS bundle.

Todo

• Fix types for the FrontendApp and createFrontend function in @awtrix/common
• Invoke Vite build programmatically to implement awtrix pack
• Add awtrix pack support for TS backends, assets and translations
• Add a Vite build watch mode for awtrix dev
• Figure out a way to run tsc --noEmit in parallel
• Figure out HMR/ restarting (via nodaemon?) for the backend
• Fix Vue (Awtrix app) component mounting for Vue 3 compatibility
• Determine if we can redo enable hot reload #2 by using the Vite dev server for awtrix dev instead of a watching build mode
• Verify npm run ... (dev) and awtrix ... (production) functionality

Looks good to me so far :)
