feat: add better support and messaging around using helm with skaffold apply

[aaron-prindle]

fixes #7101

This PR makes it so that if a single helm release is specified with a namespace option and that release is the only deployment, skaffold will set the kubectl namespace to that namespace. In the case that a helm release is specified with a namespace option and another deployment exists (eg: helm + kubectl deployments) or the case that multiple helm releases with namespaces are specified, skaffold apply will error stating:

skaffold apply called with 'deploy.helm.releases.*.namespace' field set which is not supported.  Remove the 'deploy.helm.releases.*.namespace' field(s) and run skaffold apply again

NOTE: for this to work properly, the apply call must also specify the profile used in the render call
skaffold apply -p dev --filename=skaffold.yaml manifest.yaml

^^ This is because render does not store anywhere (skaffold state, manifest files, etc) which profile was used to generate the manifests so it needs to be passed in both places
