Move black levels for tuning files that contained a BLC block into
the camera sensor helpers.
ov4689.yaml had 66@12bit while the datasheet states 64@12bit. Use the
value from the datasheet (scaled to 16bit).
ov5640.yaml had 256@12bit while the datasheet states 16@10bit. Looking
at the commit message the 256 most likely stems from the imx219 tuning
file and 16@10bit is the same as the 64@12bit from the ov4689. This
seems more likely and is therefore used.

Add sensor black levels to the metadata of the rkisp1 pipeline.
Additionally enable raw support for this algorithm and add it to
uncalibrated.yaml, so that black levels get reported when capturing
tuning images. This is a bit of a hack, because no actual black level
correction is taking place in raw mode, but it is the easiest way to get
blacklevel reported for raw streams.

Meson uses tags to sort installed files in categories, and makes it
possible to install a subset of the files using the '--tags' argument to
'meson install'. This is typically used by distributions to split the
runtime, development and documentation files into separate packages.
By default, meson tries to guess the correct tag for installed files,
but can't always do so properly. Mark the install targets that meson
can't guess with the correct install_tag.
As the feature has been introduced in meson 0.60, bump the minimum meson
version. The latest LTS release of all major distributions that
libcamera currently targets ship a recent enough meson version.

Add coefficients sets in the YAML tuning file to allow using different set
depending of the image color temperature (provided by AWB algorithm).
During processing, LSC algorithm computes coefficients by doing a linear
interpolation between the two closer set.

YAML 1.2 support has been added in libyaml in version 0.2.3. Debian
stable ships version 0.2.2 of libyaml, which causes parse errors of the
tuning tuning data files due to the YAML 1.2 directive at the beginning.
As we don't use any feature of YAML 1.2, downgrade the data files to
YAML 1.1.

Denoise and Sharpness filters will be applied by RkISP1 during the
demosaicing step. The denoise filter is responsible for removing noise
from the image, while the sharpness filter will enhance its acutance.
Add filter algorithm with denoise and sharpness values based on user
controls.

Pass the path name of the YAML IPA tuning file to the IPA module. The
file name is derived from the sensor name ("${sensor_name}.yaml"), with
a fallback to "uncalibrated.yaml".
The tuning file name can be manually overridden with the
LIBCAMERA_RKISP1_TUNING_FILE environment variable.
