Backport a minimal subset of the improvements of commit 705376f We don't backport part of the changes that implement RNTuple normalization of demangled paths. But we do apply some improvements to the renormalization of meta-normalized paths. This is a precondition to cleanly apply the series of patches fixing [U]Long64_t in template parameters.
This restriction is actually not required. (cherry picked from commit 0ce3049)
(cherry picked from commit 1648058)
Custom classes with [U]Long64_t template arguments need to use their meta-normalized name as type alias. Otherwise, during reconstruction with the RNTuple normalized name, the streamer info for the `std::[u]int64_t` argument will be requested (typically `long` instead of `long long`).

Clarify treatment of ROOT fundamental typedefs, including special treatment of `[U]Long64_t`. (cherry picked from commit b140667)
