[MLIR] Crash During GPU Module Serialization with XeGPU pipeline

Hi, I encountered a crash when lowering a gpu program using XeGPU pipeline, please review the following program for reproduction.

**Input Program**
```llvm
module attributes {gpu.container_module} {
gpu.module @kernels {
gpu.barrier
}

func.func @main() -> i32 {
%mem = memref.alloca() : memref<10xf32>
%c0_index = arith.constant 0 : index
%cst = arith.constant 3.140000e+00 : f32
memref.store %cst, %mem[%c0_index] : memref<10xf32>
%loaded = memref.load %mem[%c0_index] : memref<10xf32>
%cast = arith.fptosi %loaded : f32 to i32
memref.dealloc %mem : memref<10xf32>
return %cast : i32
}
}
```

**Stack Trace**
```bash
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.

Version: de045d579791d978cce109f9348d20560e112d74

Start by running the supplied input with `mlir-opt input.mlir --gpu-lower-to-xevm-pipeline` and inspect the serialization path in mlir/lib/Target/LLVM/XeVM/Target.cpp, along with ModuleTranslation.cpp and ModuleToObject.cpp from the stack trace. Trace the crash during GPU module serialization and add a regression test using the reproducer; done means the pipeline no longer aborts on this input.
