Release Antrea Helm chart archive for each Antrea release (#3935)

* Release Antrea Helm chart archive for each Antrea release

For each Antrea release, we generate the correct Helm chart archive and
upload it as a release asset. The appropriate index.yaml file (Helm repo
index) will be updated appropriately (in the antrea-io/website
repository) and will be accessible through charts.antrea.io and / or
antrea.io/charts.

For #2641

We are also moving all CRD resources from the generic templates/
directory to the special crds/ directory, in the Chart definition. This
will cause Helm to treat CRDs as special resources, and in particular
they will never be upgraded / deleted automatically by Helm. In
particular, for upgrade, users will need to apply a separate YAML (which
is being added to release assets) including all the CRD resource
definitions. This represents an extra step, but ensures that users are
aware that CRDs are being upgraded which may require some actions from
them (e.g., migrate to a new version) and needs to be done with caution.

Fixes #3665
