With Node.js v18 approaching End-of-Life on 2025-04-30, the minimum
supported versions for development have been updated to `^20.11.1 || ^22.11.0`.
This change does not affect published packages.
The custom ESM loader was disabled in several Node.js jasmine tests due
to incompatibilities with the updated custom loader API in newer Node.js
versions. The API in v18 was not considered stable. The rules_js migration
will remove the need for this loader fully in future.

Previously, the cross entry-point dependency was created to share the `setDomTypes` function. This however, causes extra transformations "linking" during the application build since other Angular code in `@angular/platform-server` is pulled in.
With this commit we remove the cross dependency and thus remove the need for extra transformations in the server polyfill bundle with the result of having a slightly faster build.

* Uses `.mjs` for circular deps tests
* Replaces `require` with ESM-equivalent. uses an import statement here
for proper typing, and specify dependency properly.

`@angular/platform-server` provides the foundation for rendering an
Angular app on the server. In order to achieve that, it uses a
server-side DOM implementation (currently [domino][1]).
For rendering on the server to work as closely as possible to running
the app on the browser, we need to make DOM globals (such as `Element`,
`HTMLElement`, etc.), which are normally provided by the browser,
available as globals on the server as well.
Currently, `@angular/platform-server` achieves this by extending the
`global` object with the DOM implementation provided by `domino`. This
assignment happens in the [setDomTypes()][2] function, which is
[called in a `PLATFORM_INITIALIZER`][3]. While this works in most cases,
there are some scenarios where the DOM globals are needed sooner (i.e.
before initializing the platform). See, for example, #24551 and #39950
for more details on such issues.
This commit provides a way to solve this problem by exposing a
side-effect-ful entry-point (`@angular/platform-server/init`), that
shims the `global` object with DOM globals. People will be able to
import this entry-point in their server-rendered apps before
bootstrapping the app (for example, in their `main.server.ts` file).
(See also [#39950 (comment)][4].)
In a future update, the [`universal` schematics][5] will include such an
import by default in newly generated projects.
