Add support for SpinKube WebAssembly runtime

### Description

It would be great if support for spin apps could be added.

See https://spinkube.dev

SpinKube is an implementation that allows to run webassembly in Kubernetes clusters. It was one of the hot topics at Kubecon Paris this year.

rancher desktop recently added support. https://www.suse.com/c/suses-webassembly-report-from-kubecon-eu/

not sure what exactly has to be done to make this happen. With some support of the community and figuring out the rancher desktop implementation we might be able to add support for this in Colima.

The issue mentions adding support for SpinKube WebAssembly runtime to Colima, referencing Rancher Desktop's implementation. Start by examining Colima's architecture for runtime extensions and look at how Rancher Desktop integrated Spin. The work likely involves modifying Colima's core to recognize and manage WebAssembly workloads, but the issue does not specify files or entry points.
