ipa: vc4: Implement the StatsOutputEnable vendor control

Browse source 
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.
