Fixed a memory leak in IPropertyStorage_fnDeleteMultiple when deleting properties by name. Previously, when deleting a property by its name, the code only removed the property from the propid_to_prop dictionary but failed to clean up the bidirectional mapping between property names and IDs in the propid_to_name and name_to_propid dictionaries. This resulted in orphaned dictionary entries and memory leaks. The fix ensures proper cleanup of both dictionaries when deleting properties by name by: 1. Looking up the property name in the name_to_propid dictionary 2. Removing the property from propid_to_prop dictionary 3. Also removing the bidirectional mappings from propid_to_name and name_to_propid dictionaries Signed-off-by: Jiajin Cui <cuijiajin(a)uniontech.com> -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9485
