This commit removes a number of obsolete integration tests and also removes some e2e tests for a few remianing apps, since they are not adding value, but cause extra time to spend on CI.

In Bazel, the `CI` environment variable is not set due to its hermetic nature. As a result, caching is enabled by default, which includes Vite pre-bundling. This is unnecessary in CI environments.
In some cases, this leads to errors during CI runs when the Vite build is closed or canceled prematurely, resulting in the following errors:
```
Error: R] The build was canceled
Error: R] Terminating worker thread [plugin angular-vite-optimize-deps]
```

This commit also performs lock file maintenance on all integration
tests, fixing some ambigous ESM/CJS dependency graph issues.
e.g.
```
Unknown error: Error [ERR_REQUIRE_ESM]: require() of ES Module /tmp/ng-integration-test-aTpQOT/test-sandbox/node_modules/string-width/index.js from /tmp/ng-integration-test-aTpQOT/test-sandbox/node_modules/cliui/build/index.cjs not supported.
Instead change the require of index.js in /tmp/ng-integration-test-aTpQOT/test-sandbox/node_modules/cliui/build/index.cjs to a dynamic import() which is available in all CommonJS modules.

Since we updated the devkit dependencies, we need to update
the browserslist DB versions in integration tests to avoid
browser mismatches causing errors like the following:
```
BrowserslistError: [BABEL] /tmp/ng-integration-test-91jP3g/test-sandbox/node_modules/zone.js/fesm2015/zone.js: Unknown version 114 of edge (While processing: "base$0$0")
```

Since v15, prod mode is handled by the CLI with the `optimization` flag. We can remove the environement files and `enableProdMode` when the tests use the CLI.

The Testability-related logic was refactored in https://github.com/angular/angular/pull/45657 to become tree-shaking-friendly: it was decoupled from the core providers of the `BrowserModule`. This commit updates the newly-introduced `bootstrapApplication` function to exclude Testability-providers by default (note: the Testability is still included in the NgModule-based bootstrap).
In order to add the Testability to the app bootstrapped via `bootstrapApplication`, the `provideProtractorTestingSupport` function is introduced.
PR Close#45885
This commit adds 2 integration apps to verify the `bootstrapApplication` API behavior as well as keep track of the bundle size and retained symbols (tree-shaking).
