[Feature request] dialog: Use the full folder selection dialog on windows

[axeldavy]

Hi there, I am using SDL for one of my library, and I have, as well as users, noticed that the folder selection dialog on Windows (Linux seems fine) is not very handy.

The current implementation of SDL_ShowFolderDialog on Window uses SHBrowseForFolderW.

This results in a small folder selection. Here is a screenshot (taken randomly on internet) of what it looks like:

Here is what I (and the users) would prefer:

The documentation of SHBrowseForFolderW (here) says:

For Windows Vista or later, it is recommended that you use IFileDialog with the FOS_PICKFOLDERS option rather than the SHBrowseForFolder function. This uses the Open Files dialog in pick folders mode and is the preferred implementation.

This comment suggests that the full folder selection dialog would be available if switching the implementation to IFileDialog

Thanks for the reply

Feel free to create a PR?

I'm unable to commit to such PR, not owning a Windows system and having already committed to other contributions as well as paper reviews.
