    GH-45219: [C++][Examples] Update examples to disable mimalloc (#45220)
    
    
    
    ### Rationale for this change
    
    I think the intention was to disable the default allocator which used to be 
jemalloc. However since #44951 we have switched the default allocator from 
jemalloc to mimalloc. We should update the examples.
    
    ### What changes are included in this PR?
    
    Change disabling jemalloc to disabling mimalloc for examples.
    
    ### Are these changes tested?
    
    Manually tested.
    
    ### Are there any user-facing changes?
    
    None.
