build: convert examples package to bazel (#28733)

* build: switch example e2e tests to bazel

* No longer builds the example e2e tests using "tsc". The examples are now built with Bazel and can therefore be built with Ivy by using the `--define=compile=aot` switch.
* No longer runs the example e2e tests using the protractor CLI. example e2e tests are executed with the Bazel protractor rule and can therefore run incrementally.

* test: disable failing ivy example e2e tests

*Note for patch branch:* We had to disable more examples in Ivy because
the patch branch does not contain all Ivy/ngtsc fixes.
