build: switch example e2e tests to bazel (#28402)

* 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.

NOTE: Unit tests found within the examples are still running within the legacy jobs.
