Adding origin support caused an unexpected and unwanted change in behavior where configuration property binding would fail. The failure would occur because there was no way to convert from the entry in the environment that represents the empty map to the target type. The commit changes the YAML loader to drop empty maps, effectively reverting the map portion of3bcbb0e594and gh-21704. This aligns the behavior with the decision we made in gh-19095. Origin support for an empty list has been retained as it does not have a negative effect on configuration property binding. Prior to these changes, an empty YAML list was mapped to an origin tracked value that contains an empty list. Fully reverting3bcbb0e594would have resulted in an empty YAML list being mapped to an empty string. To avoid adding a collection type to the environment, we now map an empty YAML list to an origin tracked value that contains an empty string. Closes gh-35403
