Vuestic compiler #4337

We can easily make Vuestic as rollup/vite plugin. It gives more control of user development experience with compilation step.

Features:

• CSS layers (I've done it before) - fix for issues when vuestic styles have more importance over tailwind - easy
• Extended config support - automatic TS type generations. Similar to Nuxt types generations. - medium
• Components auto-imports
  We have unplugin-auto-imports and nuxt is kind of solving this problem on it's own. - medium
• In-Component tree-shaking - remove some features from component if it is not used - something similar to feature flags. Not sure if it is possible to make automatic. - hard
• Global config without defaults. Replace defaults with values from vuestic.config.ts - easy
• Built-in devtools - hard
• Auto sync colors from vuestic.config.ts with Tailwind or UnoCSS (without cli) - medium
• Icon fonts resolver templates in build time
