Add predictions for deps.json and runtimeconfig.json files

[dfederm]

This change adds the following predictors:

• GenerateBuildDependencyFilePredictor - Makes predictions based on the GenerateBuildDependencyFile target (<project>.deps.json file)
• GeneratePublishDependencyFilePredictor - Makes predictions based on the GeneratePublishDependencyFile target. (<project>.deps.json file, when publishing)
• GenerateRuntimeConfigurationFilesPredictor - Makes predictions based on the GenerateRuntimeConfigurationFiles target. (<project>.runtimeconfig.json and <project>.runtimeconfig.dev.json files)

As well as adds the copying of those files in referencing projects to GetCopyToOutputDirectoryItemsGraphPredictor and GetCopyToPublishDirectoryItemsGraphPredictor.
