Draft: Remove the toolkit git submodule

Instead install things from npm like everything else.

rollup.utils.js was part of toolkit, but not of any published package, so just copy that for now.

marked this merge request as draft

This will have to wait until we have reached some 1.0 ish release in the toolkit. Atm we still develop things together.

But if we get back to it this could be used as inspiration.
