White balance auto temperature correlation - improve behavior with non raw files (#6903)

* Improve Itcwb with non-raw files

* Change pre-dev builds wbrefinement

* Change template in pre-dev

* Improvment improccordinator.cc

* Forgotten observer convert

* Reenable wbauto autogrey as 5.8

* Remove wrong code

* Missing getrgbloc references

* Fixed bug due to bias in queu with temperaure correlation issue 6911

* Simpleprocess queue compatibility tif-jpg

* Preserve AWB edits from 5.9

In 5.9 for non-raw files,
   1. RGB grey uses the unit multipliers with temperature bias applied.
   2. Temperature correlation uses the equivalent of temperature 5000,
      green 1, and red/blue equalizer 1.

* Refactor temperature correlation AWB code

* Fix inaccurate RGB grey WB preview after using ITC

The RGB grey automatic white balance algorithm caches the multipliers.
Temperature correlation automatic white balance also caches results to
the same location, but never uses it. This causes the RGB grey method to
produce incorrect results in the editor. Removing the temperature
correlation cache fixes the issue and does not have side-effects.
