libcamera: controls: Use vendor tags for draft controls and properties

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.
