Remove dioxus-lib, fix doc imports

[ealmloff]

Dioxus lib is currently not very useful because it doesn't include all of the exports required for rsx usage. It has also been difficult to maintain because most of the code is duplicated with the dioxus crate. This PR removes the crate

CI was also not set up to test inline documentation so a bunch of the imports were incorrect with the changes in #4416. This PR also fixes those issues and adds the test to CI

Closes #4338

This seems reasonable. Can we add a meta-feature to the dioxus crate to replace it (should not enable launch or bring in any of the renderers)?

Pulled out a lib feature without launch, devtools, or logger which should all be configured from the top level crate
