0971ea7c8b py: cam: Move conversion funcs to helpers.py
Move conversion functions from cam_qt.py to helpers.py to clean up the
code and so that they can be used from other cam renderers.

e115a69135 py: Use ln --relative to create symlinks
We create symlinks from the Python bindings build dir to the source dir
so that 1) the build dir can be used to use the bindings, and 2) to
allow modifications of the source .py files to be used right away
without rebuilding.

The symlinks were recently fixed and changed to use absolute paths.
However, absolute paths ruin one main use case I have: using the
bindings from the build dir via nfs from an ARM device.

So move back to relative paths, but accomplish this with the --relative
parameter for ln, instead of guessing the right relative path as was
done before the above-mentioned fix.

a69b73cc58 py: Generate bindings for properties
Generate bindings for properties in a very similar way as done for
controls. We do need to distinguish between the two, and thus I added

Perhaps it's better to have a more descriptive name here. I also
considered just renaming 'efd' to 'fd', but 'event_fd' won.

1698442aa8 py: Re-structure the controls API
Add ControlInfo class and change the controls related methods to
resemble the C++ API (e.g. no more string based control methods).

We don't implement ControlList or ControlInfoMap but just expose the
same data via standard Python dict.

3c82ae3821 py: Re-implement controls geneneration
The Python bindings controls generation was not very good. It only
covered the enums and they were in the main namespace.

This adds the controls somewhat similarly to the C++ side. We will have
e.g.:

libcamera.controls.Brightness
libcamera.controls.AeMeteringModeEnum.CentreWeighted
