Fix angular-bazel-example test in CI which was crashing and flaking o…

…ut (#792)

`bazel test //e2e:all` was crashing before the tests even started in CI. Possibly out of memory but not sure how that is possible as it was running in the xlarge 16GB container. This PR moves the angular-bazel-example test to its own CI job (which speeds up overall CI time as its critical path) and runs the same CI tests that angular-bazel-example runs in its own CI.
