[SHELL32]

[SHELL32]
- Simplify SHELL32_CoCreateInitSF by letting the callers fill the PERSIST_FOLDER_TARGET_INFO. This lets us stop using _ILSimpleGetTextW in it which breaks the logic that pidls should be read only by their shell folder. Also add an overload for SHELL32_CoCreateInitSF  that makes it simpler to create a shell folder with a csidl.
- Add a SHELL32_BindToSF helper to share some logic that was duplicated in several shell folders.
- Move SHELL32_GetCustomFolderAttributeFromPath, SHELL32_GetCLSIDForDirectory and SHELL32_GetFSItemAttributes, SHELL32_BindToFS to CFSFolder.cpp as these were fs specific.
- These changes give finer control to shell folders for how the bind will be done and shares more logic that can be shared.
