    Clean up dependencies for disk_cache histogram_macros.h. · 9d337bc7

    The current mechanism by which these convenience macros find their
    backend is confusing, at best; the macro has the form of our include
    guard macros, but describes a CC file. Embedded within the
    histogram_macros.h then is an abstraction violation: it just knows
    which object has backend information depending on which file it was
    included from.
    
    Some downstream reviews have made this even more confusing; rather
    than continue this, let's parameterize the backend object to the
    convenience macros, so each translation unit is responsible for
    knowing its own context.
