Turn off track refit for FTF in trigger for ITk

Elliot Watton requested to merge ewatton/athena:ewatton_FTFITkNoTrackRefit into main

As title describes, this MR turns off the track refit for running FTF for ITk in the trigger (default setting is True). This is what has been done in the offline version of running FTF for quite a while (!60362 (merged)) and should also be applied to the trigger version given that the same seeding and track following tools are used. As a result, we should see a slight speedup in algorithm CPU time for FTF. This MR targets main as changes only affect ITk, however, as this changes the TrigFastTrackFinderCfg method used for both Run 3 and Run 4, let me know if this MR needs to target 24.0.

Tagging @baines, @smh, @demelian, @jmasik
