Subject: [PATCH] Fix windows only build failure on include filename.

Between eliding third_party directory names in includes, and Windows being case insensitive on header include paths, the following include was ambiguous and resolved to (1), leading to issues in using the StableHLO header:

```
#include "stablehlo/transforms/Passes.h"
// (1) tensorflow/compiler/mlir/lite/stablehlo/transforms/passes.h
// (2) @stablehlo - third_party/stablehlo/stablehlo/transforms/Passes.h
```
