A class name in a selection XML can span multiple lines. `CleanType()` only treated `' '` as a blank, so a newline was kept in the cleaned name and, when the template arguments were later re-processed individually, an argument starting with a newline was truncated to an empty string. This corrupted the rootmap entries and the alternate name registrations (e.g. `"Foo<,vector<float>,>"`), leading to `"Second registration of ..."` errors from `TClassTable::AddAlternate` at library load time. Treat all whitespace like a space: drop it where a space would be dropped, and emit a single plain space where it separates two identifiers. Closes root-project#22359. 🤖 Done with the help of AI. (cherry picked from commit 9d59a11)
