Support slash/backslash as path separator instead of platform-specific path separator

Describe the feature

In the environment where a lot of files have the same name but are in different folders it is handy to search for partial path. For example, C++ CMake build system uses a lot of CMakeLists.txt files for build targets (libraries, apps, tests, etc). This means project generally has more than a handful of these files.

Pretty much every sufficiently modern editor/IDE nowadays has File Finder like functionally which I use it most of the time when navigating around project. I've tested VS Code, Sublime Text, IntelliJ IDEA and Qt Creator and all of them are able to match files regardless of path separator.

Quick skim through the Zed sources revealed use of std::path::MAIN_SEPARATOR_STR which is platform dependant.

So to be explicit, your request is that both / and \ are supported as path separators regardless of which platform you are running Zed.

I wonder if this behavior makes sense universally or in a subset of:

• 'File Finder' (cmd-p) - Your suggestion
• Global Find in Files (include/exclude globs)
• Open/Save As (with fallback picker use_system_path_prompts)
• Project Panel: Create new file: a/b/c/file.txt and a\b\c\file.txt
• Assistant /file picker

I can confirm that other editors (Sublime Text, VSCode, etc) on macOS allow using \ as a path separator in the file finder and project search include/exclude which surprised me.
