This adds initial support for extracting and rendering call and construct
signatures of classes, like within the new `InputFunction` for signal
inputs.
For now, signatures are a rare occasion and represented as class member
entries. In the future we might consider exposing this via its own entry
type, and field on the class/interface entry.

Enables signal inputs for existing Zone based components.
This is a next step we are taking to bring signal inputs earlier to the Angular community.
The goal is to enable early access for the ecosystem to signal inputs, while we are continuing
development of full signal components as outlined in the RFC. This will allow the ecosystem
to start integrating signals more deeply, prepare for future migrations, and improves code quality
and DX for existing components (especially for OnPush).
Based on our work on full signal components, we've gathered more information and learned
new things. We've improved the API by introducing a way to intuitively declare required inputs,
as well as improved the API around initial values. We even support non-primitive initial values
as the first argument to the `input` function now.
```ts
@Directive({..})
export class MyDir {
firstName = input<string>(); // string|undefined
lastName = input.required<string>(); // string
age = input(0); // number
```

The version of rxjs used to build the repository has been updated to v7.
This required only minimal changes to the code. Most of which were type
related only due to more strict types in v7. The behavior in those cases
was left intact. The most common type related change was to handle the
possibility of `undefined` with `toPromise` which was always possible with
v6 but the types did not reflect the runtime behavior. The one change that
was not type related was to provide a parameter value to the `defaultIfEmpty`
operator. It no longer defaults to a value of `null` if no default is provided.
To provide the same behavior the value of `null` is now passed to the operator.

The `nodejs-websocket` package has been replace with the `ws` package.
Both provide `WebSocket` server support and both of zero transitive
dependencies. However, the `ws` package has ~78 million weekly downloads
and was last updated this week (as of the writing of this commit) while
the `nodejs-websocket` package has ~7,600 weekly downloads and was last
update 5 years ago. The `ws` package is also already a transitive dependency
of the repository which allows for a reduction in the total dependency count
for the repository.

The `graceful-fs` package itself is unused within the repository code
and can be removed. The resolution workaround is no longer required
for any direct or transitive dependency based on the issue referenced
via #28213.

Two TypeScript type definition packages are currently unused within the
repository and can be removed. These were most likely leftover from previous
usage of the related packages.
Packages removed:
* `@types/uuid`
* `@types/cli-progress`

The `base64-js` package was only used in tests that were run only on
Node.js. On Node.js, `Buffer` is available which can natively perform
base64 conversion. By using `Buffer in these Node.js only tests, the
`base64-js` package can be removed from the repository.

The `multimatch` package was only used in the saucelabs test bundling
script to filter out spec files that should be ignored during saucelabs
testing. This functionality can be replaced with `fast-glob` package's
`ignore` option. This removes the need for the `multimatch` package within
the repository.

Several unused babel related dependencies can be removed:
* `@babel/preset-env` was previously used for ngcc tests but ngcc has been removed. It used here: 3569fdf451/packages/compiler-cli/ngcc/test/BUILD.bazel (L84)
* `@babel/helper-replace-supers` was added during a manual lock file update to workaround issues with since removed babel packages

The `@babel/core` package provides the functionality of multiple other babel packages
without the need to directly depend or import the other babel packages. Since the
`@babel/core` package is already used and imported in the locations that previously
used the other babel packages, an overall reduction in both imports and dependencies
is possible. Six babel related packages were able to be removed from the root `package.json`
and one (also present in the aforementioned six) was removed as a dependency from the
`@angular/localize` package. Unfortunately, the functionality used from the `@babel/generator`
package is not provided by `@babel/core` and is still present. Further refactoring may
allow its removal as well in the future.
The following packages were removed:
* @babel/parser
* @babel/template
* @babel/traverse
* @babel/types
* @types/babel__template
* @types/babel__traverse
