    GH-49898: [C++][CI] Use mold in more builds (#49899)
    
    ### Rationale for this change
    
    We're currently using the mold linker only on a couple of C++ builds. This 
PR uses it in more builds to get faster link times and thus faster CI builds.
    
    ### Are these changes tested?
    
    Yes, by CI builds.
    
    ### Are there any user-facing changes?
    
    No.
