Path.cs does not round trip when used to read a file from a directory and then to execute file operations

### What You Are Seeing?

[Path.cs](https://github.com/cake-build/cake/blob/dfdadb1b84804bfc3782597346a1dadc7bbdba89/src/Cake.Core/IO/Path.cs#L66) will convert all `\` to `/`, even if `'\'` is part of the *file name* on macOS.

The result is that the `CleanDirectories` command fails if any file includes a`'\'` in its name. For example: If `/users/user/source/bad\file.txt` exists, and Cake runs `CleanDirectories("/users/user/source")`, then the task will fail to find `/users/user/source/bad/file.txt` in order to delete it, and fail.

### What is Expected?

I would expect `CleanDirectories` to not *fail*. I would expect paths to round-trip.

### What version of Cake are you using?

31.0 - I'd expect all versions to be affected.

### Are you running on a 32 or 64 bit system?

64

### What environment are you running on? Windows? Linux? Mac?

macOS

### Are you running on a CI Server? If so, which one?

No

### How Did You Get This To Happen? (Steps to Reproduce)

This is a simple problem to reproduce.
Repeated from above:
If `/users/user/source/bad\file.txt` exists, and Cake runs `CleanDirectories("/users/user/source")`.

Specifically, I ran into this because `log4net` generated a "bad" file using a config that works as intended on Windows.
```

...
```

### Output Log

`build.sh` executes Cake using:
```
exec mono "$CAKE_EXE" --paths_tools=cake -experimental "$@"
```

The Clean task looks like:
```
Task("Clean")
.Does(() =>
{
CleanDirectories($"src/**/bin");
CleanDirectories($"src/**/obj");
CleanDirectories($"tests/**/bin");
CleanDirectories($"tests/**/obj");
CleanDirectory("release");
});
```

Start in src/Cake.Core/IO/Path.cs, especially the path conversion described around line 66, and reproduce the macOS case with a filename containing a backslash. Verify the fix by running CleanDirectories on that directory and confirming the original path round-trips and the file operation does not fail.
