fix(make): Ensure Python 3 compatibility

[nerdCopter]

The build script make.py was using ctypes to monkey-patch the built-in str type for path separator conversion. This approach is not compatible with Python 3 and caused the script to fail.

This commit refactors the script by removing the ctypes-based "magic code" and replacing it with a simple fix_path helper function. All calls to the old .path property have been updated to use this new, more robust function.

fixes:

$ ./make.py -T=F3
Traceback (most recent call last):
  File "/home/ndronet/SYNC/nerdCopter-GIT/imu-f_nerdRepo/./make.py", line 64, in <module>
    get_dict(str)['path'] = get_path_method
    ^^^^^^^^^^^^^
  File "/home/ndronet/SYNC/nerdCopter-GIT/imu-f_nerdRepo/./make.py", line 56, in get_dict
    return _get_dict(object).contents.value
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Pull Request Overview

This PR fixes Python 3 compatibility issues in the make.py build script by removing unsafe ctypes-based monkey-patching of the built-in str type and replacing it with a simple helper function for path separator conversion.

• Removed complex ctypes code that was causing crashes in Python 3
• Added a simple fix_path() helper function for cross-platform path handling
• Updated all references from .path property calls to fix_path() function calls
