Add an option to use '\' instead of '/' as a file path separator when using "Copy Absolute Path" in the editor's FileSystem dock

Describe the problem or limitation you are having in your project

Using the new "Copy Absolute Path" option introduced in PR #90421, the file path that is copied uses forward slash '/' as the file path separator. On windows this makes it difficult to use in combination with native programs such as the Windows File Explorer. For example, copying a Godot folder's absolute path and pasting it into Windows File Explorer's "path to extract zipped folder to" prompt returns an error until I manually replace each forward slash '/' with a backslash '\'.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Add an option in the Editor Settings to use backslashes '\' instead of forward slashes '/' when getting/copying OS file paths. This way, the path copied from the editor can be directly pasted into windows programs that don't accept forward slashes.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

In Editor Settings/FileSystem/Directories:

...

• Use Backslashes in OS File Paths (On/Off)
• [Hover Description]: When enabled, file and folder paths copied from Godot will use backslashes () instead of forward slashes (/) as the file path separator. This will increase compatibility with Windows programs, which oftentimes will require paths to use backslashes so that they conform to the Windows filesystem. It is not recommended to enable this setting when working on non-Windows platforms, which generally use forward slashes. Enabled by default on Windows platforms.

Now in the Godot FileSystem dock:

• Right click on a file or folder
• Copy absolute path copies "C:\Users\user\Documents\godot\new-game-project\folder" instead of "C:/Users/user/Documents/godot/new-game-project/folder" for example

If this enhancement will not be used often, can it be worked around with a few lines of script?

This would require editing the functionality of PR #90421 and the Editor Settings, and any other places in the editor that give you OS file paths to copy, which would involve editing the C++ source of the Godot Engine.

Is there a reason why this should be core and not an add-on in the asset library?

It is not intrusive and would be useful to most Windows users when working with the Windows filesystem and Godot.

But Windows File Explorer supports both slash types 🤔

Some old Windows apps won't let you paste paths with forward slashes in them, so I think we should always convert to backslash when copying an absolute path on Windows. Godot accepts both forms either way.

I don't think this needs to be an editor setting – we should just always do it :slightly_smiling_face:

Well on the other hand, some apps only accept forward slashes. E.g. VS Code JSON config only supports forward paths, and ironically copying file paths in the same program gives you backward-slash, so it's incompatible with itself.

Though GIMP is one of the programs that only supports backward slashes on Windows. It's generally inconsistent, hence option makes sense, as it depends on your workflow.
