Partial back-port of the first commit of #24184 (limiting to L1, anything beyond would require full backport of #24184).

Tested in CMSSW_10_2_9, no changes expected.

@makortel Thanks.
I believe @ssekmen includes in the PR already, #25683 already.

[makortel]

@srimanob Well, yes, as @ssekmen's PR is in master branch (which has dropped L1 from premix stage1 for all workflows in #24184). So this PR is orthogonal to #25683.

And now I notice that this PR is incomplete (it still includes L1 in 2017 FastSim premix stage1), I'll fix shortly.

[makortel]

Actually, closer inspection reveals that removing L1 from FastSim premix stage1 is not that simple (and my earlier testing was insufficient), so I'll close this PR.
