Certain dependencies such as `@octokit/rest`, `remark` and `@babel/*` have not been updated as they require a decent amount of work to update, and it's best to leave them for a seperate PR.

* We had a usage of `Observable.subscribe` that uses the deprecated signature with 3 arguments. These changes switch to the non-deprecated version that passes in an `Observer`.
* Avoids always creating a `complete` callback since it isn't required.
* We were repeating all of the internal callbacks twice: once for sync and once for async. These changes move them out into variables so that they're more minifier-friendly. The savings aren't huge (~100 bytes minified), but it doesn't add any maintenance effort on our end so I decided to add it.

With this change we move `XhrFactory` to the root entrypoint of `@angular/commmon`, this is needed so that we can configure `XhrFactory` DI token at a platform level, and not add a dependency between `@angular/platform-browser` and `@angular/common/http`.
Currently, when using `HttpClientModule` in a child module on the server, `ReferenceError: XMLHttpRequest is not defined` is being thrown because the child module has its own Injector and causes `XhrFactory` provider to be configured to use `BrowserXhr`.
Therefore, we should configure the `XhrFactory` at a platform level similar to other Browser specific providers.
BREAKING CHANGE:
`XhrFactory` has been moved from `@angular/common/http` to `@angular/common`.
**Before**
```ts
import {XhrFactory} from '@angular/common/http';
```
**After**

This commit makes the `RadioControlRegistry` class tree-shakable by adding the `providedIn` property to its

Currently the `Validators` class contains a number of static methods that represent different validators as well as some helper methods. Since class methods are not tree-shakable, any reference to the `Validator` class retains all of its methods (even if you've used just one).
This commit refactors the code to extract the logic into standalone functions and use these functions in the code instead of referencing them via `Validators` class. That should make the code more tree-shakable. The `Validators` class still retains its structure and calls these standalone methods internally to keep this change backwards-compatible.

This commit updates Forms code to avoid direct references to all built-in ControlValueAccessor classes, which

Previously, injector definitions contained a `factory` property that
was used to create a new instance of the associated NgModule class.
Now this factory has been moved to its own `ɵfac` static property on the
NgModule class itself. This is inline with how directives, components and
pipes are created.
There is a small size increase to bundle sizes for each NgModule class,
because the `ɵfac` takes up a bit more space:
Before:
```js
let a = (() => {
class n {}
return n.\u0275mod = c.Cb({type: n}),
n.\u0275inj = c.Bb({factory: function(t) { return new (t || n) }, imports: [[e.a.forChild(s)], e.a]}),
n
})(),
```
After:
```js
let a = (() => {
class n {}
return n.\u0275fac = function(t) { return new (t || n) },
n.\u0275mod = c.Cb({type: n}),
n.\u0275inj = c.Bb({imports: [[r.a.forChild(s)], r.a]}),
n
})(),
```
In other words `n.\u0275fac = ` is longer than `factory: ` (by 5 characters)
and only because the tooling insists on encoding `ɵ` as `\u0275`.
This can be mitigated in a future PR by only generating the `ɵfac` property
if it is actually needed.

There are two parts to this commit:
1. Revert the changes from #38379. This change had an incomplete view of
how things worked and also diverged the implementations of
`applyRedirects` and `recognize` even more.
2. Apply the fixes from the `recognize` algorithm to ensure that named
outlets with empty path parents can be matched. This change also passes
all the tests that were added in #38379 with the added benefit of being
a more complete fix that stays in-line with the `recognize` algorithm.
This was made possible by using the same approach for `split` by
always creating segments for empty path matches (previously, this was
only done in `applyRedirects` if there was a `redirectTo` value). At the
end of the expansions, we need to squash all empty segments so that
serializing the final `UrlTree` returns the same result as before.

When a `ViewContainerRef` is injected, we dynamically create a comment node next to the host
so that it can be used as an anchor point for inserting views. The comment node is inserted
through the `appendChild` helper from `node_manipulation.ts` in most cases.
The problem with using `appendChild` here is that it has some extra logic which doesn't return
a parent `RNode` if an element is at the root of a component. I __think__ that this is a performance
optimization which is used to avoid inserting an element in one place in the DOM and then
moving it a bit later when it is projected. This can break down in some cases when creating
a `ViewContainerRef` for a non-component node at the root of another component like the following:
```
<root>
<div #viewContainerRef></div>
</root>
```
In this case the `#viewContainerRef` node is at the root of a component so we intentionally don't
insert it, but since its anchor element was created manually, it'll never be projected. This will
prevent any views added through the `ViewContainerRef` from being inserted into the DOM.
These changes resolve the issue by not going through `appendChild` at all when creating a comment
node for `ViewContainerRef`. This should work identically since `appendChild` doesn't really do
anything with the T structures anyway, it only uses them to reach the relevant DOM nodes.
Fixes#39556.

Currently when an instance of the `FormControlName` directive is destroyed, the Forms package invokes
the `cleanUpControl` to clear all directive-specific logic (such as validators, onChange handlers,
etc) from a bound control. The logic of the `cleanUpControl` function should revert all setup
performed by the `setUpControl` function. However the `cleanUpControl` is too aggressive and removes
all callbacks related to the onChange and disabled state handling. This is causing problems when
a form control is bound to multiple FormControlName` directives, causing other instances of that
directive to stop working correctly when the first one is destroyed.
This commit updates the cleanup logic to only remove callbacks added while setting up a control
for a given directive instance.
The fix is needed to allow adding `cleanUpControl` function to other places where cleanup is needed
(missing this function calls in some other places causes memory leak issues).

In ViewEngine, SelfSkip would navigate up the tree to get tokens from
the parent node, skipping the child. This restores that functionality in
Ivy. In ViewEngine, if a special token (e.g. ElementRef) was not found
in the NodeInjector tree, the ModuleInjector was also used to lookup
that token. While special tokens like ElementRef make sense only in a
context of a NodeInjector, we preserved ViewEngine logic for now to
avoid breaking changes.
We identified 4 scenarios related to @SkipSelf and special tokens where
ViewEngine behavior was incorrect and is likely due to bugs. In Ivy this
is implemented to provide a more intuitive API. The list of scenarios
can be found below.
1. When Injector is used in combination with @Host and @SkipSelf on the
first Component within a module and the injector is defined in the
module, ViewEngine will get the injector from the module. In Ivy, it
does not do this and throws instead.
2. When retrieving a @ViewContainerRef while @SkipSelf and @Host are
present, in ViewEngine, it throws an exception. In Ivy it returns the
host ViewContainerRef.
3. When retrieving a @ViewContainerRef on an embedded view and @SkipSelf
is present, in ViewEngine, the ref is null. In Ivy it returns the parent
ViewContainerRef.
4. When utilizing viewProviders and providers, a child component that is
nested within a parent component that has @SkipSelf on a viewProvider
value, if that provider is provided by the parent component's
viewProviders and providers, ViewEngine will return that parent's
viewProviders value, which violates how viewProviders' visibility should
work. In Ivy, it retrieves the value from providers, as it should.
These discrepancies all behave as they should in Ivy and are likely bugs
in ViewEngine.

Prior to this commit, the `cleanUpControl` function (responsible for cleaning up control instance)
was not taking validators into account. As a result, these validators remain registered on a detached
form control instance, thus causing memory leaks. This commit updates the `cleanUpControl` function
logic to also run validators cleanup.
As a part of this change, the logic to setup and cleanup validators was refactored and moved to
separate functions (with completely opposite behavior), so that they can be reused in the future.
This commit doesn't add the `cleanUpControl` calls to all possible places, it just fixes the cases
where this function is being called, but doesn't fully perform a cleanup. The `cleanUpControl`
function calls will be added to other parts of code (to avoid more memory leaks) in a followup PR.
