Use the new Vite Runtime API to support server-side HMR correctly

[garrappachc]

Describe the problem

Currently used vite.ssrLoadModule() doesn't support the HMR API fully. Vite doesn't call hot.dispose/hot.accept functions for invalidated modules, thus making server-side long-living tasks (i.e. setInterval() or event listener callbacks) stack on top of each other each time a reload happens.

Describe the proposed solution

Call runtime.executeEntrypoint() instead of vite.ssrLoadModule().

Second this. Would be a very helpful improvement.

I experience the same problem with WebSocket httpServer which is started in Svelte's hooks.server.ts - it remains running and throwing EADDRINUSE (port/address in use).
