[SHELL32] File Types dialog: Add functionality, optimize loading time (#6122)

- Support loading protocols like XP
- Support most of the relevant EditFlags
- Support reading/writing the AlwaysShowExt and BrowserFlags properties
- Loads the list much faster with optimized code and delaying the large icon and description string
- Reduce the number of magic buffer sizes by replacing them with defines that are in the ballpark of being correct
- Implemented column sorting
- Removed custom icon extraction code
- Removed IDS_FILE_EXT_TYPE string because it must be the same as IDS_ANY_FILE
- Don't touch verb keys that are not edited to retain the original REG type
- Don't clobber unchanged %1 icon location when editing a type
