Add dependency tracking to the Python code generation (#772)

This ensures that the Python source files are only generated and copied
into the output directory if inputs have changed, rather than being done
unconditionally.

Builds on the similar change made in binaryninja-api in
Vector35/binaryninja-api@3e2ace5
