Add Microsoft.Windows/RegistryList resource

[SteveL-MSFT]

PR Summary

Enhance the registry resource to also have a Microsoft.Windows/RegistryList type which contains an array of Microsoft.Windows/Registry entries.

• Bumped version to 1.1
• Remove tracing from registry lib since it doesn't get emitted anyways
• Simplify the code to always work off a list, so when used as Microsoft.Windows/Registry, the code just wraps it in a list handled in import_input() function
• Added new constructor in registry lib to take a Registry instance instead of JSON as that will get used iterating through the list
• Moved to a single registry.dsc.manifests.json file containing both resources
• registry.exe for get and set have a new --list switch indicating the new mode
• changed existing debug traces to trace since they emit the raw information which could be sensitive
