G-API: New python operations API * Reimplement test using decorators * Custom python operation API * Remove wip status * python: support Python code in bindings (through loader only) * cleanup, skip tests for Python 2.x (not supported) * python 2.x can't skip unittest modules * Clean up * Clean up * Fix segfault python3.9 Co-authored-by: Alexander Alekhin <alexander.a.alekhin@gmail.com>
