export `processIncludes` method

Is your feature request related to a problem? Please describe.

I want to render the raw markdown that is processed inside vitepress. I can use createMarkdownRenderer and renderInline, but the @includes content is not imported. I want to include the processed markdown, including any markdown-it and @include evaluation, as a build asset for my VitePress site.

Describe the solution you'd like

I found a way to do this using the internal processIncludes method, if it was exported that would make this code easy to implement:

  buildEnd: async (config: SiteConfig) => {
    const mdR = await createMarkdownRenderer(config.srcDir, config.markdown, config.site.base, config.logger)
    const file = `${config.srcDir}/markdown-examples.md`
    const md_raw = await readFile(file, 'utf-8')
    const md_src = processIncludes(config.srcDir, md_raw, file, [])
    console.log("md", mdR.renderInline(md_src))
  }

I had to manually copy the function from the compiled code, but it works and would be useful.

Another alternative is to add a processIncludes flag to the createMarkdownRenderer function, so that I can decide to renderInline with or without it.
