HLT GPU tutorial

[fwyzard]

PR description:

Implement a tutorial for using GPUs in CMSSW.

The outline is:

• take a collection of PF jets
• convert to SoA format
• [automatically] copy to device
• read jet corrections from the EventSetup
• apply the corrections based on pT and |eta|
• produce a SoA with corrected jets
• apply some cuts based on pT and |eta|
• compute the invariant mass of all combinations of 2 or 3 jets
• select all combinations with invariant mass in a given range
• fill a SoA with all combinations of (j1, j2, n/a) or (j1, j2, j3)
• [automatically] copy to host
• print the combinations of PF jets

This PR includes the bug fixes from #47605.

PR validation:

The tutorial runs successfully on top of CMSSW_15_0_0.
