Static site generation is a CLI feature for sites with sitemaps

[ealmloff]

Feature Request

The current static site generation package is just a way to build a sitemap and then use that sitemap to generate static html for each page

Implement Suggestion

We could add sitemap generation support to fullstack and remove the need for a static generation page by just adding sitemaps as an option for fullstack. You could then emulate a static file server for fullstack with a setting in the dioxus.toml or a flag in the CLI that:

1. Builds fullstack
2. Launches the fullstack server
3. Fetches the /sitemap.xml file
4. Fetches any urls the sitemap links to and copies the resulting html into the dist directory
5. Shuts down the fullstack server
6. Serves static files from the prebuilt dist directory
