SOLR-13241: Add 'autoscaling' tool to solr.cmd
Prior to this commit, SOLR-13155 added support for an 'autoscaling' tool
to bin/solr, but not to the Windows equivalent bin/solr.cmd. This
commit adds the necessary plumbing to the Windows version of this
script. It also removes some dead help-text from the bin/solr script.

> Solr already provides /autoscaling/diagnostics and /autoscaling/suggestions
> endpoints. In some situations it would be very helpful to be able to run
> "what if" scenarios using data about nodes and replicas taken from a
> production cluster but with a different autoscaling policy than the one that
> is deployed, without also worrying that the calculations would negatively
> impact a production cluster's Overseer leader.
> All necessary classes (including the Policy engine) are self-contained in the
> SolrJ component, so it's just a matter of packaging and writing a CLI tool +
> a wrapper script.
