Fix Duplicate conflicting deployments with DeployAllMultipleTemplateParameterFiles

[Jefajers]

Overview/Summary

This PR changes two key pieces to fix #886 and avoid incorrect recursive parameter discovery.

1. Adjusts how the $deploymentName is derived at run-time. Ensuring that if the deployment job que contains overlapping deployments, we only process it once when they have matching deployment name and files.
   1. Addressing Duplicate conflicting deployments performed when enabling DeployAllMultipleTemplateParameterFiles and ParallelDeployMultipleTemplateParameterFiles #886
2. During recursive parameter discovery there was a possibility that a un-related file pair would have been discovered and queued for processing. This is not the intent so a step in the recursive process has been added to regex match the base name of any discovered files prior to any further processing.
