libcamera: software_isp: Define skeletons for IPA refactoring

Software ISP image processing algorithms are currently defined in a
simplified way, different from other libcamera pipelines.  This is not
good for several reasons:

- It makes the software ISP code harder to understand due to its
  different structuring.
- Adding more algorithms may make the code harder to understand
  generally.
- Mass libcamera code changes may not be easily applicable to software
  ISP.
- Algorithm sharing with other pipelines is not easily possible.

This patch introduces basic software ISP IPA skeletons structured
similarly to the other pipelines.  The newly added files are currently
not used or compiled and the general skeleton structures don't contain
anything particular.  It is just a preparation step for a larger
refactoring and the code will be actually used and extended as needed in
followup patches.
