Prevent memory hoarding for GetClass("int") or any other numerical types.

This addresses https://root-forum.cern.ch/t/repeatedly-mapping-branches-slowly-fills-memory/63412.
This fix #18536.

This relates to #9029 but does not solve it completely. It solves the sub-cases of #9029 where the typedef is known to TROOT::GetListOfTypes.

Thanks for this. We'll need also the backport for 6.36 ideally.
