Use eta dependent pT cut for trigger implementation for FTF ITk

As the title says, this changes the pT cut used when running FTF in ITk to be eta-dependent (as is done in offline). In this way we improve efficiency in both the barrel and endcaps by up to 5%. There is a compromise in speed due to more combinatorics possible, however, this will be counteracted by a separate MR which will make use of the new tracking tools that are designed to lead to speed-up in the combinatorial tracking step of FTF.

This MR was in draft state to be checked by @tamartin and @baines. They have now checked it and have given the ok from their side.

(This MR is linked with the changes made in !72450 (merged)).
