Backport of PR#9 to CMSSW_12_3_0

[elfontan]

An updated full set of xml files for the L1 emulation of prescales and masks coherent with the updated v1_0_0 L1 menu for Run 3 is provided in #9.
I would like to ask for the backport of the PR to CMSSW_12_3_0 in order to have a coherent set of menu and PS+mask tables in the release.

Sure @elfontan! Changes will be backported to CMSSW_12_3_0 in PR #7770 once it passes the tests.

Many thanks,
Andrea.
