GroupComponents function: Allow registering multiple components in a single tuple/array

[Avokadoen]

When creating the storage, allow nest tuples of components by simply tagging the neste tuple so that the collection is not parsed as a component:

const group_a = ecez.GroupComponents(.{MyComponentA0, MyComponentA1, MyComponentA2 });
const group_b = ecez.GroupComponents(&[_]type{MyComponentB0, MyComponentB1, MyComponentB2 });

ecez.CreateStorage(.{
        group_a,
        group_b,
        SingleComponent, 
        // ...
    }, .{});

CreateStorage can support single depth neste array of types. Then, all GroupComponents does is convert to convert a tuple/struct of components into an array of component types

UnpackComponents migth be a better name
