2024-08-16py: gen-py-controls: Use Control classLaurent Pinchart
Replace manual extraction of data from YAML with the Control helper class. This centralizes YAML parsing and avoids manual mistakes. In order to import the controls module, add the utils/codegen/ directory to the PYTHONPATH through the Python build environment.

2024-08-16meson: utils: Provide environment for Python scriptsLaurent Pinchart
Python scripts run as part of the build process need to take a few actions specific to the environment in which they operate. One of those is disabling the Python bytecode cache, to avoid writing .pyc files to the source tree. This is done manually in the IPC generate.py and parser.py scripts. The current implementation is not ideal because it hardcodes in the scripts information related to the environment in which they operate. As those scripts are part of libcamera this is more of a theoretical issue than a practical one. A second issue is that future Python scripts will need to duplicate similar mechanisms, resulting in a higher maintenance burden. Address the issue with a different approach, by creating a meson environment for the Python scripts, and passing it to the custom_target() functions. The environment only disables the bytecode cache for now. The diffstat shows an increase in code size. This is expected to be offset by usage of the environment for more Python scripts, as well as support of more variables in the environment.

2024-08-15meson: Move all code generation scripts to utils/codegen/Laurent Pinchart
We have multiple code generation scripts in utils/, mixed with other miscellaneous utilities, as well as a larger code base based on mojom in utils/ipc/. To make code sharing easier between the generator scripts, without creating a mess in the utils/ directory, move all the code generation code to utils/codegen/.
