To reduce code duplication, use the Pwl class from libipa. This also
removes the Pwl class from the Raspberry Pi IPA.

Add new CAC, HDR, Saturation and Tonemapping algorithms.
Add a new Denoise algorithm that handles spatial/temporal/colour denoise
through one interface. With this change, the old SDN algorithm is now
considered deprecated and a warning message will be displayed if it is
enabled.

This commit does the basic reorganisation of the code in order to
implement multi-channel AGC. The main changes are:
* The previous Agc class (in agc.cpp) has become the AgcChannel class
in (agc_channel.cpp).
* A new Agc class is introduced which is a wrapper round a number of
AgcChannels.
* The basic plumbing from ipa_base.cpp to Agc is updated to include a
channel number. All the existing controls are hardwired to talk
directly to channel 0.
There are a couple of limitations which we expect to apply to
multi-channel AGC. We're not allowing different frame durations to be
applied to the channels, nor are we allowing separate metering
modes. To be fair, supporting these things is not impossible, but
there are reasons why it may be tricky so they remain "TBD" for now.
This patch only includes the basic reorganisation and plumbing. It
does not yet update the important methods (switchMode, prepare and
process) to implement multi-channel AGC properly. This will appear in
a subsequent commit. For now, these functions are hard-coded just to
use channel 0, thereby preserving the existing behaviour.

Split the Raspberry Pi pipeline handler and IPA source code into common
and VC4/BCM2835 specific file structures.
For the pipeline handler, the common code files now live in
src/libcamera/pipeline/rpi/common/
and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/.
For the IPA, the common code files now live in
src/ipa/rpi/{cam_helper,controller}/
and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the
camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/.
To build the pipeline and IPA, the meson configuration options have now
changed from "raspberrypi" to "rpi/vc4":
meson setup build -Dipas=rpi/vc4 -Dpipelines=rpi/vc4
