build: migrate @angular-devkit/build-angular tests to rules_js

Migrates the `@angular-devkit/build-angular` tests to `rules_js`. This
was a rather larger undertaking as the tests were very reliant on e.g.
the directory structure or specific node module layout; so some changes
were needed.

- the Sass files include a much larger file header now. That is because
  the npm Sass files have much larger paths, given being inside a
  symlinked pnpm store directory. E.g.

  ```

/*!**********************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************!*\
  !*** css ../../../../../node_modules/.aspect_rules_js/[email protected]_webpack_5.97.1/node_modules/css-loader/dist/cjs.js??ruleSet[1].rules[4].rules[0].oneOf[0].use[1]!../../../../../node_modules/.aspect_rules_js/[email protected]_1462687623/node_modules/postcss-loader/dist/cjs.js??ruleSet[1].rules[4].rules[0].oneOf[0].use[2]!./src/test-style-a.css?ngGlobalStyle ***!
  \**********************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************/
.test-a {color: red}
  ```

- Similarly to above, hashed chunk files can change given different
  paths of e.g. Webpack, or external sources.

- Tests for verifying the lazy module chunks may enable
  `preserveSymlinks` just to make the chunk names shorter and easier to
  verify, avoiding truncatd super long paths to the e.g. pnpm stores
  again.

- the ngsw-worker.js file cannot be copied using `copyFile` as that
  results in permissions being copied as well. In Bazel, now that
  the npm files are properly captured, are readonly, so subsequent
  builds (e.g. the watch tests) will fail to copy/override the file
  again! Reading and writing the file consistently seems appropriate.

- Tests relying on puppeteer and webdriver-manager worked in the past,
  by accident, because postinstall scripts (from e.g. puppeteer) were
  able to modify content of other packages (e.g. the puppeteer-core
  cache of browsers then). This does not work with `rules_js` anymore,
  so we need to keep the cache local to the puppeteer postinstall
  script. This requires a little trickery right now to ensure resolution
  of the browsers at runtime works..

- server tests did miss the `node` types to be explicitly listed (as
  they would be in a fresh project), and this caused failures. Likely
  because we no longer patch resolution.

- avoid npm-module style imports from tests within the same package.
  This is not allowed with `rules_js` and also is inconsistent.
