  [MLIR] Generic 'malloc', 'aligned_alloc' and 'free' functions

When converted to the LLVM dialect, the memref.alloc and memref.free operations were generating calls to hardcoded 'malloc' and 'free' functions. This didn't leave any freedom to users to provide their custom implementation. Those operations now convert into calls to '_mlir_alloc' and '_mlir_free' functions, which have also been implemented into the runtime support library as wrappers to 'malloc' and 'free'. The same has been done for the 'aligned_alloc' function.

  Log Message:
  [mlir] move _mlir_alloc and friends to CRunnerUtils

These functions don't depend on the C++ runtime and therefore belong to
CRunnerUtils. Clean up the macros on the way as `_MSC_VER` indicates the
compiler, not the platform, which is indicated by `_WIN32` and will be
present when, e.g., compiling with minGW.
