Misko Hevery 22880eae16 feat(ivy): add debug view of internal deta structures (#28945)
This change contains conditionally attached classes which provide human readable (debug) level
information for `LView`, `LContainer` and other internal data structures. These data structures
are stored internally as array which makes it very difficult during debugging to reason about the
current state of the system.

Patching the array with extra property does change the array's hidden class' but it does not
change the cost of access, therefore this patching should not have significant if any impact in
`ngDevMode` mode. (see: https://jsperf.com/array-vs-monkey-patch-array)

So instead of seeing:

```
Array(30) [Object, 659, null, …]
```

```
LViewDebug {
  views: [...],
  flags: {attached: true, ...}
  nodes: [
    {html: '<div id="123">', ..., nodes: [
      {html: '<span>', ..., nodes: null}
    ]}
  ]
}
```
