test(ivy): Have more descriptive names for LView (#33449)

Browse Source 
When debugging `LView`s it is easy to get lost since all of them have
the same name. This change does three things:

1. It makes `TView` have an explicit type:
  - `Host`: for the top level `TView` for bootstrap
  - `Component`: for the `TView` which represents components template
  - `Embedded`: for the `TView` which represents an embedded template
2. It changes the name of `LView` to `LHostView`, `LComponentView`, and
  `LEmbeddedView` depending on the `TView` type.
3. For `LComponentView` and `LEmbeddedView` we also append the name of
  of the `context` constructor. The result is that we have `LView`s which
  are name as: `LComponentView_MyComponent` and `LEmbeddedView_NgIfContext`.

The above changes will make it easier to understand the structure of the
application when debugging.

NOTE: All of these are behind `ngDevMode` and will get removed in
production application.
