[PWGDQ] added derived tables to global muon alignment task

[aferrero2707]

The derived tables provide the minimal information neederd to run the alignment analysis on new geometries, thus avoiding to pocess each time the original large-size AO2Ds.

A pre-processor switch allows to use the same task for either producing or processing the derived tables.

@mcoquet642 @javierecc @ppoava here is another relatively urgent PR, that should allow to iterate over the alignment geometries much faster with small derived tables.

I still need to rebase once #17743 is merged, but you can already have a look at the changes if you have the time.

Thanks!

@mcoquet642 I looked at the changes. This look fine to me but I believe it is better if you take a quick look before merging

[aferrero2707]

@mcoquet642 @mguilbau note that the changes only affect the task we use for the in-depth analysis of the global muon alignment, and do not touch other parts of the DQ code.

Unless there are serious errors reported by the code-check, it should be good to go.

[mguilbau]

No serious error reported indeed. I will approve it then
