Add estimator states to sfmdata

[servantftechnicolor]

Goal :

• cleanup
• Be able to provide multiple policies in an easier way

LocalBundleAdjustment was storing the state of the sfmData properties (constant, ignored, refined) as a set of map.

Here we just move this information in the sfmData distributed in the various structures.

I kept the original structure and duplicate the information for the moment to keep the test working. It will need an update when the new classes will be used.

Looks all good to me. I renamed the EParameterState enum into EEstimatorParameterState since the link with the BA is not obvious anymore from the name alone and clang'ed the modified files.
