@FrontendInterface to generate frontend interface

[sveinnetnordic]

When using ReactAdapterElement, @ClientCallable, executeJs etc its a manual job to create a Typescript interface. If they do not match no error is shown, but fails in runtime.

Please add something like:

@FrontendInterface
public record RgbaColor(int r, int g, int b, double a)

that generates:

export interface  RgbaColor {
    r: number;
    g: number;
    b: number;
    a: number;
}

The workaround for this is to create a dummy @BrowserCallable with all the needed types as parameters

Yes, I have done that for some years 😄 Today @BrowserCallable needs Hilla too, which I do not need (don't need frontend routing)

While the types generation is Hilla's responsibility, the detection of @FrontendInterface being added to a project is a Flow feature.
