Description

### Description of the bug:

Namaste,

While attempting to build using bazel by pointing buildkite toward a RAM mounted file system
I see the following error. I'm not sure under what conditions `blaze_util::MakeCanonical` fails on Windows.

```
[FATAL 12:14:05.257 src/main/cpp/blaze.cc:1302] blaze_util::MakeCanonical('r:\buildkite-agent\builds\windows-amd64-mustang-1\yesudeep\rules-clojure') failed: (error: 1): Incorrect function.
```

### What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

1. Create a RAM disk using [ImDisk](https://www.tenforums.com/tutorials/174094-how-create-ram-disk-imdisk-windows-10-a.html)
2. Point your CI agent to use the Ram disk.
3. Have it run bazel there.

### Which operating system are you running Bazel on?

Windows 11 Pro

### What is the output of `bazel info release`?

release 6.0.0

### If `bazel info release` returns `development version` or `(@non-git)`, tell us how you built Bazel.

_No response_

### What's the output of `git remote get-url origin; git rev-parse master; git rev-parse HEAD` ?

_No response_

### Any other information, logs, or outputs that you want to share?

- [ ] The problem is not reproducible if I switch to drive mounted at C: (SSD) instead of R: (RAM FS)

Research direction

Start with src/main/cpp/blaze.cc around line 1301 and src/main/cpp/util/file_windows.cc around line 482, then reproduce the failure on a Windows 11 ImDisk RAM disk. Compare the same Bazel build on the R: RAM disk and a C: SSD drive. Done means the target builds successfully on the RAM disk without the MakeCanonical error.
