Currently we save a reference to an `LView` on most DOM nodes created by Angular either by saving the `LView` directly in the `__ngContext__` or by saving the `LContext` which has a reference to the `LView`. This can be a problem if the DOM node is retained in memory, because the `LView` has references to all of the child nodes of the view, as well as other internal data structures. Previously we tried to resolve the issue by clearing the `__ngContext__` when a node is removed (see https://github.com/angular/angular/pull/36011), but we decided not to proceeed, because it can slow down destruction due to a megamorphic write. These changes aim to address the issue while reducing the performance impact by assigning a unique ID when an `LView` is created and adding it to `__ngContext__`. All active views are tracked in a map where their unique ID is used as the key. We don't need to worry about leaks within that map, because `LView`s are an internal data structure and we have complete control over when they are created and destroyed. Fixes #41047.
