Label draft controls and properties through the "draft" vendor tag
and deprecate the existing "draft: true" mechanism. This uses the new
vendor tags mechanism to place draft controls in the same
libcamera::controls::draft namespace and provide a defined control id
range for these controls. This requires moving all draft controls from
control_ids.yaml to control_ids_draft.yaml.
One breaking change in this commit is that draft control ids also move
to the libcamera::controls::draft namespace from the existing
libcamera::controls namespace. This is desirable to avoid API breakages
when adding new libcamera controls. So, for example, the use of
controls::NOISE_REDUCTION_MODE will need to be replaced with
controls::draft::NOISE_REDUCTION_MODE.

Add support for using separate YAML files for controls and properties
generation. The mapping of vendor/pipeline handler to control file is
done through the controls_map variable in include/libcamera/meson.build.
This simplifies management of vendor control definitions and avoids
possible merge conflicts when changing the control_ids.yaml file for
core and draft controls. With this change, libcamera and draft controls
and properties files are designated the 'libcamera' vendor tag.
In this change, we also rename control_ids.yaml -> control_ids_core.yaml
and property_ids.yaml -> property_ids_core.yaml to designate these as
core libcamera controls.

The template file to the gen-controls.py and gen-py-controls.py is now
passed in through the '-t' or '--template' command line argument instead
of being a positional argument. This will allow multiple input files to
be provided to the scripts in a future commit.

Add support for vendor-specific controls and properties to libcamera.
The controls/properties are defined by a "vendor" tag in the YAML
control description file, for example:
vendor: rpi
controls:
- MyExampleControl:
type: string
description: |
Test for libcamera vendor-specific controls.
This will now generate a control id in the libcamera::controls::rpi
namespace, ensuring no id conflict between different vendors, core or
draft libcamera controls. Similarly, a ControlIdMap control is generated
in the libcamera::controls::rpi namespace.
A #define LIBCAMERA_HAS_RPI_VENDOR_CONTROLS is also generated to allow
applications to conditionally compile code if the specific vendor
controls are present. For the python bindings, the control is available
with libcamera.controls.rpi.MyExampleControl. The above controls
example applies similarly to properties.
Existing libcamera controls defined in control_ids.yaml are given the
"libcamera" vendor tag.
A new --mode flag is added to gen-controls.py to specify the mode of
operation, either 'controls' or 'properties' to allow the code generator
to correctly set the #define string.
As a drive-by, sort and redefine the output command line argument in
gen-controls.py and gen-py-controls.py to ('--output', '-o') for
consistency.

The python bindings layer has to parse the libcamera controls to ensure
that they are converted to suitable names for the python layer.
Part of this strips out common prefixes from control names, however the
SceneFlicker control would end up using an illegal name if processed in
the same way as the other controls.
The SceneFlicker control has now been removed as part of the
introduction of the AeFlickerMode and AeFlickerPeriod controls.
Remove the workaround in the python layer.

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
--properties flag to gen-py-controls.py.

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
