refactor: switch macros to @angular/cli

[alexeagle]

Greatly simplifies code, and works with the npm deps users already take. Otherwise we have to instruct them to add @Angular-devkit packages to their devDeps.

Also includes fixes to make it work with Angular v20 which has slightly different dependencies and different angular.json

I've updated aspect-build/bazel-examples#417 to the new /src path.

I have one error there I could use some eyes on, from running bazel test //angular/projects/my-lib:test which is tagged no-sandbox:

Application bundle generation failed. [2.859 seconds]

✘ [ERROR] File '../../../../src/lib/my-lib.spec.ts' is missing from the TypeScript compilation. [plugin angular-compiler]

  Ensure the file is part of the TypeScript program via the 'files' or 'include' property.


✘ [ERROR] Could not resolve "@angular/core/testing"

    ../../../../../../../node_modules/.aspect_rules_js/@angular+build@20.0.0-next.3_1309402193/node_modules/@angular/build/src/builders/karma/polyfills/init_test_bed.js:9:27:
      9 │ import { getTestBed } from '@angular/core/testing';
        ╵                            ~~~~~~~~~~~~~~~~~~~~~~~

  You can mark the path "@angular/core/testing" as external to exclude it from the bundle, which will remove this error and leave the unresolved path in the bundle.

The second error looks legit. The @angular/build package seems to miss this dependency (as esbuild seems to pick it up from where it's defined?) https://github.com/angular/angular-build-builds/blob/main/package.json. cc. @clydin

@clydin hi again! Any time or interest in investigating that second error with missing dependency edge? Do you want me to file an issue on another repo?
