Update Phase 2 HLT timing test (post #48921)

[mmusich]

PR description:

The goal of this PR is twofold.
Following the merge of PR #48921, part of the Phase 2 HLT menu (the chain from pixel digis to pixel tracks and vertices) now can run on GPU. As the HLT phase2 timing test is run on a "Milan" node equipped with NVIDIA T4s, this on one hand has improved the general timing of the menu, but on the other hand it doesn't give back a realistic picture of the time needed to run when no GPU backed is available, for example when running MC productions.
The first goal of this PR is ensure that part of the timing tests run on CPU.
At the same time, it is now possible to be more aggressive with the reconstruction used in the NGT menu to avoid running full tracking on all events accepted by the L1T, but profiting of the phase 2 CA extension implemented in #48921 use the pixel track collection as "general" track collection for the rest of the HLT reconstruction (analogously to what done in runTheMatrix.py for workflow family XXXXX.774).
