replace HLTP2GTTauFilter with an instace of HLTP2GTSingleObjectFilter

[mmusich]

PR description:

Title says it all, with the integration of #51669 we can retire HLTP2GTTauFilter as it is superseded by the more general HLTP2GTSingleObjectFilter.

PR validation:

• cmssw compiles.
• runTheMatrix.py -l ph2_hlt -i all --ibeos runs fine.
• Bitwise trigger results compatibility to be tested by the bot.
