2022-05-10py: Fix gen-py-control-enums.py referenceKieran Bingham
Scripts should be referenced using the meson files() directive to ensure the location is correctly identified with the relevant paths. This prevents compilation failures if the working directory does not match the source tree.

2022-05-10py: Add cam.pyTomi Valkeinen
Add cam.py, which mimics the 'cam' tool. Four rendering backends are added: * null - Do nothing * kms - Use KMS with dmabufs * qt - SW render on a Qt window * qtgl - OpenGL render on a Qt window All the renderers handle only a few pixel formats, and especially the GL renderer is just a prototype.

2022-05-10py: Generate control enums from yamlTomi Valkeinen
Generate enums for controls from control_ids.yaml. The generator script has some heuristics to generate nicer enum names. E.g. instead of having "LensShadingMapMode.LensShadingMapModeOff" we get "LensShadingMapMode.Off". This heuristics may need to be updated when the yaml file is changed or new controls are added.

2022-05-10Add Python bindingsTomi Valkeinen
Add libcamera Python bindings. pybind11 is used to generate the C++ <-> Python layer. We use pybind11 'smart_holder' version to avoid issues with private destructors and shared_ptr. There is also an alternative solution here: https://github.com/pybind/pybind11/pull/2067 Only a subset of libcamera classes are exposed. Implementing and testing the wrapper classes is challenging, and as such only classes that I have needed have been added so far.
