[mlir] Hotfix - Fix Windows build

This revision adds a static `mlir_c_runner_utils_static` library
for the sole purpose of being linked into `mlir_runner_utils` on
Windows.

It was previously reported that:
```

`add_llvm_library(mlir_c_runner_utils SHARED CRunnerUtils.cpp)`

produces *only* a dll on windows, the linking of mlir_runner_utils fails
because target_link_libraries is looking for a .lib file as opposed to a
.dll file. I think this may be a case where either we need to use
LINK_LIBS or explicitly build a static lib as well, but I haven't tried
either yet.
```
