Fix: Update desktop Recycle Bin icon after bin operations (Fixes #9946)

[myselfsiddharth]

Fixes #9946

Summary

The Windows desktop Recycle Bin icon now updates after recycle bin operations performed in Files.

• Added UpdateDesktopRecycleBinIcon() to IStorageTrashBinService and implemented it in StorageTrashBinService using the existing SHUpdateRecycleBinIcon P/Invoke
• Call icon refresh after: empty bin, restore all, send to recycle bin, restore items, and permanently delete from bin
• Fixed RestoreAllTrashesInternal to only refresh the icon and return success when PerformOperations succeeds

Test plan

• Move a file to the bin from Files → desktop icon shows full bin
• Empty the bin from Files → desktop icon shows empty bin
• Restore a file from the bin → desktop icon updates correctly
• Permanently delete from the bin → desktop icon updates correctly
• Restore all from the bin → desktop icon shows empty bin
