Use EmbedIO instead of Embed IO (#2645)
- ⚠️ Depends on #2644 

The `effectful` library does not support the `Embed` effect out of the
box. However, it offers `IOE`, which is equivalent to `Embed IO` from
polysemy. In preparation to a possible migration to `effectful`, this pr
hides the general `Embed` effect from the prelude and it exports a
specialized `EmbedIO` in its place.
