Add coefficients sets in the YAML tuning file to allow using different set
depending of the image color temperature (provided by AWB algorithm).
During processing, LSC algorithm computes coefficients by doing a linear
interpolation between the two closer set.

LSC gradient parameters are currently computed during prepare() phase.
Because these parameters can be computed only one time and stay constant for
each frame after, move the computation to the configure() function.

Multiple algorithms have an initialized_ flag that they set to true at
the end of the init() function, and check at the beginning of prepare()
to skip preparation. This serves no real purpose, as the flag can only
be false if init() fails, in which case the IPA module initialization as
a whole will fail.
Drop the initialized_ flags.

Pass the current frame number, and the current FrameContext for calls to
prepare.

Add an enable variable in the lsc struct in IPASessionConfiguration
which indicates if the LSC hardware module is enabled. This will allow
other algorithms to retrieve this information.

The Lens Shading Correction algorithm applies multipliers to all pixels
to compensate for the lens shading effect. The coefficients are
specified in a downscaled table in the YAML tuning file.
