Inclusion of the displaced jet bit

[elfontan]

Preliminary implementation of the displaced jet bit as an info for jet objects coming from the Calo Layer 2.
We have a 1-bit LUT where the value can be only 0-1.
Reference JIRA Ticket: CMSLITDPG-963.

Open items:

1. Name of the variable in the L1AnalysisL1UpgradeDataFormat --> final implementation in the emulator not available yet
2. Do we need to read a specific LUT like for the Iso or IP?

The displaced jet bit hasn't officially been added to L1AnalysisL1UpgradeDataFormat already.
The full L1 emulator (Calo L1, L2, jet algo) by Gillian, along with the modifications to save the jet HwQual bit in the L1TNtuple, are in this commit.

In the JetBxCollection, the jet quality word (hwQual) is accessed with a jet iterator, it->hwQual(). The first bit of jet hwQual (bit 27) as a 1 bit LUT is used: 0 if the jet is not found to be delayed, and 1 if it is (meaning 2 LLP-flagged trigger towers are contained within it).

We have two reference PRs:

• PR#36919 for the L1 and L2 Calo emulator, mostly relevent for our implementation;
• PR#36858 for the uGT emulator.
