Make ssr settings less strict

I need to prerender certain pages in ssg mode, so some chunks should be trasnformed with ssr: true option.
However, this condition: https://github.com/solidjs/vite-plugin-solid/blob/master/src/index.ts#L377 requires in my plugin change option explicitly:

function setSSRMode(enable: boolean) {
  if (enable) {
     options.solidPluginOptionsRef.ssr = true
     options.solidPluginOptionsRef.solid!.hydratable = false
  } else {
     options.solidPluginOptionsRef.ssr = _ssr
     options.solidPluginOptionsRef.solid.hydratable = _hydratable
  }
}

async function getEntryFragment(entry: NormalizedEntry) {
  setSSRMode(true)
  const ssrMod = await server.ssrLoadModule(entry.ssrEntry, { fixStacktrace: true })
  setSSRMode(false)
  if (ssrMod.render?.constructor !== Function) {
     throw new Error(`SSG entry ${entry.ssrEntry} should provide 'render' export`)
  }
  const fragment = await ssrMod.render()
  return fragment
}

I suggest something like:

const generate = options.ssr || isSsr ? 'ssr' : 'dom'
const hydratable = isSsr || options.ssr

solidOptions = {
  generate,
  hydratable
};

Start with src/index.ts around line 377, where the SSR option is currently required, and compare that condition with the proposed generate and hydratable settings. Trace how the Vite plugin options are applied during SSG and verify that selected chunks can use ssr: true without requiring external option mutation.
