    GH-47537: [C++] Use pkgconfig name for benchmark in Meson (#47538)
    
    ### Rationale for this change
    
    Because of an inconsistency in the name of the pkgconfig file for google 
benchmark and the dependency exposed by Meson, Meson will always ignore a 
system install and fallback to building google benchmark locally. We can 
instead patch our Meson configuration to workaround the inconsistent naming
    
    ### What changes are included in this PR?
    
    We use the proper pkgconfig exposed name to find the dependency, and 
fallback to the Meson subproject / variable name combination as necessary
    
    ### Are these changes tested?
    
    Yes
    
    ### Are there any user-facing changes?
    
    No
