Delete Physics "tag" packages

We no longer produce TAG files and certainly not for physics analysis. Delete the following obsolete packages (neither of which has seen any relevant updates in years apart from code migrations, one reason to finally get rid of them):

• StandardModelPhysTagTools
• SUSYPhysTagTools
• HiggsPhysTagTools
• HeavyIonPhysTagTools

For reference, other related cleanups are:

• ExoticPhysTagTools (!38080 (merged))
• BPhysTagTools (!38078 (merged))

The CP-related tag packages will follow in a separate MR.
