ipa: ipu3: Add the functions to the Algorithm class

Introduce three functions in the Algorithm class to manage algorithms:
- configure which is called when IPA is configured only
- prepare called on EventFillParams event at each frame when the request
is queued
- process called on EventStatReady event at each frame completion when
the statistics have been generated.

The existing AGC implementation already has a function named process(),
though it has different arguments. Adding the new virtual process()
interface causes a compiler warning due to the AGC implementation
overloading a virtual function, even though the overload can be resolved
correctly.

Temporarily disable the warning in this commit to maintain bisection
until the AGC is converted to the new interface.
