[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
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.
