Currently the golden output of the circular-deps tool is purely
based on the order of source files passed to the tool, and on the
amount of imports inside source files.
This is actually resulting in deterministic output as running
the tool multiple times without any changes to source files,
results in the same output.
Though it seems like the tool is too strict and we can avoid
unnecessary golden changes if:
1. A source file that is part of a cycle is imported earlier (in terms
of how the analyzer visits them). This could result in the cycle path
starting with a different source file.
2. Source files which are not part of a cycle are imported earlier
(in terms of how the analyzer visits them). This could result in moved
items in the golden if re-approved (even though the cycles remain the same)
To fix this, we normalize the cycle path array that serves as
serializable data structure for the text-based goldens. Since
the paths represents a cycle, the path can be shifted in a
deterministic way so that cycles don't change unnecessarily
in the golden, and to simplify comparison of cycles.
Additionally, we sort the cycles in a deterministic way so
that the golden doesn't change unnecessarily (as explained above).

The matcher is allowed to return null per
https://angular.io/api/router/UrlMatcher#usage-notes
And run `yarn gulp format` to pick up recent clang format changes.
Closes#29824
BREAKING CHANGE: UrlMatcher's type now reflects that it could always return
null.
If you implemented your own Router or Recognizer class, please update it to
handle matcher returning null.

Prior to this commit, the `packages/core/src/render3/interfaces/query.ts` file used to import `QueryList` using `../../linker`, which contains a lot of re-exports and as a result, this one import caused a lot of circular deps cycles reported by the tool that checks such deps. In other places in the code the `QueryList` is imported using more narrow import (`linker/query_list`), so this commit uses the same pattern. This change allowed to reduce the number of known cycles from 343 to 207, the golden file was updated accordingly.

`KeyValuePipe` currently accepts `null` values as well as `Map`s and a
few others. However, due to the way in which TS overloads work, a type
of `T|null` will not be accepted by `KeyValuePipe`'s signatures, even
though both `T` and `null` individually would be.
To make this work, each signature that accepts some type `T` has been
duplicated with a second one below it that accepts a `T|null` and
includes `null` in its return type.

This commit augments the `FactoryDef` declaration of Angular decorated
classes to contain information about the parameter decorators used in
the constructor. If no constructor is present, or none of the parameters
have any Angular decorators, then this will be represented using the
`null` type. Otherwise, a tuple type is used where the entry at index `i`
corresponds with parameter `i`. Each tuple entry can be one of two types:
1. If the associated parameter does not have any Angular decorators,
the tuple entry will be the `null` type.
2. Otherwise, a type literal is used that may declare at least one of
the following properties:
- "attribute": if `@Attribute` is present. The injected attribute's
name is used as string literal type, or the `unknown` type if the
attribute name is not a string literal.
- "self": if `@Self` is present, always of type `true`.
- "skipSelf": if `@SkipSelf` is present, always of type `true`.
- "host": if `@Host` is present, always of type `true`.
- "optional": if `@Optional` is present, always of type `true`.
A property is only present if the corresponding decorator is used.
Note that the `@Inject` decorator is currently not included, as it's
non-trivial to properly convert the token's value expression to a
type that is valid in a declaration file.
Additionally, the `ComponentDefWithMeta` declaration that is created for
Angular components has been extended to include all selectors on
`ng-content` elements within the component's template.
This additional metadata is useful for tooling such as the Angular
Language Service, as it provides the ability to offer suggestions for
directives/components defined in libraries. At the moment, such
tooling extracts the necessary information from the _metadata.json_
manifest file as generated by ngc, however this metadata representation
is being replaced by the information emitted into the declaration files.
