[NanoAOD, JMENanoAOD] Backport of #33824 (Remove jercVars variables, update puId config) to 11_2_X

[nurfikri89]

Backport from #33824

PR description:

This PR aims to

• Remove certain jercVars variables from the main NanoAOD but still keep them in the JMENano.
• Update configurations for pileup Id in JMENano.

With this PR, the event size for the main Nano is reduced from 2.90 kb/event to 2.86 kb/event. The comparison was made using 5K events from a TTJets RunIISummer20UL17MiniAODv2 sample. No event size changes for JMENano.

if this PR is a backport please specify the original PR and why you need to backport that PR:

Original PR is #33824

backport inline with master
(not strictly needed backport in 11_2 but can be useful if jmenano will be produced in 11-2 in the future)

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_11_2_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_0_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
