Lenny Maiorani e4ce485309 CMake: Decouple cmake utility functions from top-level CMakeLists.txt
Problem:
- These utility functions are only used in `AK`, but are being defined
  in the top-level. This clutters the top-level.

Solution:
- Move the utility functions to `Meta/CMake/utils.cmake` and include
  where needed.
- Also, move `all_the_debug_macros.cmake` into `Meta/CMake` directory
  to consolidate the location of `*.cmake` script files.
