This patch adds the unit and integration test suite for the pythonmaker
tool.
The test is orchestrated by a Python script and uses a "golden file"
comparison method. It runs `pythonmaker` on a comprehensive test IDL
and verifies that the generated `.pyi` output exactly matches a set of
pre-validated reference stubs.
The test is integrated into the build system and runs with 'make check'.
