ECH and ECE ccs template migration updated (#3312)

I've updated the ECE and ECH docs to migrate from the legacy / removed
CCS template to a standard template, as the dedicated template is no

-The cross-cluster search deployment template is now deprecated and has been removed from the {{ecloud}} Console. You no longer need to use the dedicated cross-cluster template to search across deployments. Instead, you can now use any template to [configure remote clusters](ec-enable-ccs.md) and search across them. Existing deployments created using this template are not affected, but they are required to migrate to another template before upgrading to {{stack}} 8.x.
