Protect TauSpinnerTable producer against crash with samples with HTT mixed with other processes

[mbluj]

PR description:

This PR fixes TauSpinnerTableProducer (introduced in #45828) against an issue caused by samples with events containing the H->tau,tau (HTT) decay mixed with events without this decay. Examples of such samples were discussed in https://cms-talk.web.cern.ch/t/higgs-in-wz-amcatnlofxfx-samples/55138.

The nanoAOD production crashes in such samples as the TauSpinnerTableProducer produces a non-empty table for events with the HTT decay while empty one for events without it which leads to an inconsistent output across different events which then confuses the output module.

The fix consists of producing tables with default weights for events without HTT ensuring consistency, but for price of producing not needed numbers. To be noted that similar strategy is employed in case of HTXS tables. Overhead due to this should be limited as tables with constant values are efficiently compressed.

PR validation:

Validated by processing samples with events containing the HTT decay, without the HTT decay and mixed with and without.
