Also removes `build:remote --spawn_strategy=remote` from .bazelrc. It seems that with Bazel 1.0.0 setting `--incompatible_list_based_execution_strategy_selection=false` no longer works around the issue with npm_package that it did when it was added. The error that was originally observed has returned after updating to Bazel 1.0.0:
```
ERROR: /home/circleci/ng/packages/angular_devkit/build_optimizer/BUILD:66:1: Assembling npm package packages/angular_devkit/build_optimizer/npm_package failed: No usable spawn strategy found for spawn with mnemonic Action. Your --spawn_strategy, --genrule_strategy or --strategy flags are probably too strict. Visit https://github.com/bazelbuild/bazel/issues/7480 for migration advice
```
This commit removes both `—incompatible_list_based_execution_strategy_selection=false` as well as `build:remote --spawn_strategy=remote` which means that Bazel will do the default behavior of picking the first available strategy from the default list, which is `remote,worker,sandboxed,local`. See https://github.com/bazelbuild/bazel/issues/7480 for more details.

After this PR is merged, maintainers no longer need to update .bazelrc
file, toolchain and platform related flags for RBE builds and tests
(unless there is a breaking change in Bazel related to those flags).
Maintainers just need to update the pin of @bazel-toolchains repo
regularly in the packages/bazel/package.bzl file according to
https://releases.bazel.build/bazel-toolchains.html to include the
latest checked-in toolchain configs. If rbe_autoconfig() cannot find
appropriate toolchain configs for the version of Bazel in the version of
@bazel_toolchains repo that is currently used by this project, it will pull
down the container and generate the configs on the fly as the beginning
of the build/test.

The `web_workers/images` example is not being tested by any e2e
spec and therefore it's technically not necessary to fix that it uses
external resources, though in order to ensure that the Bazel builds
are hermetic and that we can eventually add e2e specs for the
web_worker/image example, we should avoid any use of external
resources.
We remove the `web-animations` polyfill in the `web_workers/animations`
example because we should try to vendor as few as possible deps. Also
the animations API is already supported by browsers we run the e2e tests
against (note here: `web_workers/animations` is currently also disabled)

Currently the "routing" playground example fails the e2e tests
because it tries to load the OpenSans font using an external
HTTP request. External http requests are not allowed (unless
explicitly enabled) within Bazel in order to ensure that
all targets are built and tested in a hermetic way.
In order to work around this issue in a Bazel idiomatic way,
we just vendor the fonts in the "third_party" folder. Note
that we can technically also enable internet for the RBE
host platform, but it's not a best practice for hermeticity.
The following syntax would allow us to enable internet for
RBE (stated here for tracking)
```
properties: {
name: "dockerNetwork"
value: "standard"
}
```
