Remove Test nightly Cranelift workflow

Cranelift makes api breaking changes often enough that this workflow
fails half of the time. As such in practice I completely ignore it's
result and push an update to a branch after Cranelift branches to test
everything on CI. In this update I immediately fix the fallout of api
breaking changes.
