HLT update with new menu AND L1 update - 72X

HLT update with new menu but before L1 update - 72X

This PR adds a new frozen menu for run-1 relval workflows and IB tests.
It also uses new-style naming conventions for symbolic GTs, keeping
the old one for backward compatibility.

The 73X version of this PR is #5531.

I have just updated this PR with the HLT menus to use the new L1.
Thus the update also adds the L1 PRs #5529 and #5575.
It also updates again the addOn IB tests.

Following PR #5581, we now also set useLegacyError=TRUE in StripCPE, as is done by RECO.
