The switchMode, prepare and process methods are updated to implement
multi-channel AGC correctly:
* switchMode now invokes switchMode on all the channels (whether
active or not).
* prepare must find what channel the current frame is, and run on
behalf of that channel.
* process updates the most recent DeviceStatus and statistics for the
channel of the frame that has just arrived, but generates updated
values working through the active channels in round-robin fashion.
One minor detail in process is that we don't want to change the
DeviceStatus metadata of the current frame, so we now pass this to the
AgcChannel's process method, rather than letting it find the
DeviceStatus in the metadata.

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.

Add a new helper function Histogram::interBinMean() that essentially
replaces the existing Histogram::interQuantileMean() logic but working on
bins instead.
Rework the interQuantileMean() to call into interBinMean() with the
appropriate convertion from quatiles to bins.

The Agc::process() function returns an AgcStatus object in the
metadata as before, but Agc::prepare() is changed to return the values
it computes in a separate AgcPrepareStatus object (under the new tag
"agc.prepare_status").
The "digitalGain" and "locked" fields are moved from AgcStatus to
AgcPrepareStatus.
This will be useful going forward as we can be more flexible about the
order in which prepare() and process() are called, without them
trampling on each other's results.

We now time-filter the exposure before sorting out how much digital
gain is required. This is actually a little more natural and
simplifies the code. It also prepares us for some future work where
this arrangement will be helpful.

prepare() doesn't use the AWB status, so fetching it in process() is
probably better. This change is preparatory to other changes, where we
may find ourselves calling process() without having called prepare()
previously.

The FocusFom metadata was no longer being reported back because the

Additionally, the scaling of the focus FoMs was over-zealous, rounding

The imx708 must drop a single frame on startup - but only when in HDR
mode. Non-HDR modes do not need to drop frames. Fix the logic in
hideFramesModeSwitch() which currently unconditionally advertises to
drop one frame.
Unfortunately there is no clear way to tell if the sensor is in the HDR
mode. So for now, look the resolution and framerate to deduce this.
Additionally ensure we override hideFramesStartup() and return the same
number as hideFramesModeSwitch().

In commit 0ee9339331c6, a default metering/exposure/constraint mode is
used if a control sets a mode that is not listed in the camera tuning
file.
Setting a default mode may be undesirable in these cases, so instead
keep the agc mode unchanged. This also matches the behaviour for other
IPA controls where no changes are made in error conditions.

If a metering/exposure/constraint mode is not listed in the sensor
tuning file, and a control for the missing mode is set on the agc, we
terminate the application with a fatal log message.
Instead of this fatal termination, log a warning message and switch to
the appropriate default mode so that the application continues running.
