Auto exposing API from preload

[cawa-93]

Experimentally added support for automatic exposing of api from preload package.

Now, for everything you export from the preload will be automatically called electron.contextBridge.exposeInMainWorld.

// preload/index.ts
export function hash(data: string) { // Will be available in renderer context
}

And to access the exposed API in the renderer you need to import them from the #preload

// renderer/index.ts
import {hash} from '#preload'
hash('string') // Will be runs in preload context
