[🐞] v2: nested projections

[thejackshelton]

Which component is affected?

Qwik Runtime

Describe the bug

 In the case of the logical tree with nested projections in the same component, we need to
 persist the depth of the projection

 Nested projection VNodes can occur only in case of nested slots. For example:

 ```tsx
 <Comp1> <-- has slot
   <Comp2> <-- has slot
      <Slot />
   </Comp2>
 </Comp1>
 ```
 
 Reproduction:

    import { component$ } from '@builder.io/qwik';
import { Slot } from '@builder.io/qwik';

export default component$(() => {
 return (
   <CompOne>
     <div>Hey</div>
   </CompOne>
 );
});

export const CompOne = component$(() => {
 return (
   <CompTwo>
     <CompThree>
       <Slot />
     </CompThree>
   </CompTwo>
 );
});

export const CompTwo = component$(() => {
 return (
   <div>
     <Slot />
   </div>
 );
});

export const CompThree = component$(() => {
 return (
   <div>
     <Slot />
   </div>
 );
});
    ```
