Make Software Rendering no_std compatible

This updates the dependencies such that the software rendering is now
`no_std` compatible. However this still won't entirely work, as the
`rendering` feature itself isn't fully `no_std` compatible yet. `lyon`
is the only crate remaining however that still needs to be made `no_std`
compatible.
