There was a circular dependency between platform.py and preprocessor.py: - Platform stores Macro and MacroFunction objects; and - MacroExpander requires a Platform. Breaking this dependency enables Platform arguments in preprocessor.py to be decorated with the correct type-hints. This code structure is also a better reflection of how Platform is used by the preprocessor. Signed-off-by: John Pennycook <john.pennycook@intel.com>

Pull Request Overview
This PR resolves a circular import dependency between platform.py and preprocessor.py by moving the Platform class definition from platform.py to preprocessor.py, enabling proper type hints for Platform arguments in the preprocessor module.
- Move
Platformclass fromplatform.pytopreprocessor.py - Delete the now-empty
platform.pyfile - Update all import statements to use
preprocessor.Platforminstead ofplatform.Platform

Proposed changes
Platformdefinition from platform.py to preprocessor.pyplatform.Platformto usepreprocessor.Platforminstead.Reviewing the code, it is clear that a
Platformdoesn't really represent a "platform" in the sense we mean it elsewhere. It's really something like a "preprocessor state", and we construct a differentPlatformfor each file in a codebase. As a follow-up to this PR I intend to renamePlatformand tidy it up, but I wanted to make sure simply moving the class didn't break anything before going further.
