Implement the StatsOutputEnable control for the VC4 IPA. When set,
this outputs the ISP statistics as a uint8_t span through the Bcm2835StatsOutput
metadata control.
To get this working, IpaBase::libcameraMetadata_ is moved from a private
to a protected member variable. This makes it accessable to the VC4
derived IPA class.

Add a virtual IpaBase::platformStart() member function that is called
at the end of IpaBase::start(). For the IpaVc4 derived class, this
function does nothing, but will be used in the PiSP derived class to
reset internal state on startup.

We handle the flicker modes by passing the correct period to the
AEC/AGC algorithm which already contains the necessary code.
The "Auto" mode, as well as reporting the detected flicker period via
the "AeFlickerDetected" metadata, are unsupported for now.

Do not advertise colour related controls (i.e. [A]WB, colour saturation)
in the ControlInfoMap of available controls returned out to the
application.
Silently ignore these controls in the control handler in case applications
don't use the advertised ControlInfoMap to validate controls.
As a drive-by fix, don't advertise controls::ColourCorrectionMatrix in
the ControlInfoMap as it is not handled by the IPA.

Create a new IpaBase class that handles general purpose housekeeping
duties for the Raspberry Pi IPA. The implementation of the new class
is essentially pulled from the existing ipa/rpi/vc4/raspberrypi.cpp file
with a minimal amount of refactoring.
Create a derived IpaVc4 class from IpaBase that handles the VC4 pipeline
specific tasks of the IPA. Again, code for this class implementation is
taken from the existing ipa/rpi/vc4/raspberrypi.cpp with a
minimal amount of refactoring.
The goal of this change is to allow third parties to implement their own
IPA running on the Raspberry Pi without duplicating all of the IPA
housekeeping tasks.
