LOG: [libc++][test] Move backported algorithms to `libcxx/test/support` (#199431)

And namespace `util`. This will make helpers provided more consistently,
and potentially allow us to unify test helper namespaces in the future.

Added: 
    libcxx/test/support/algorithms.h

Modified: 
    

Removed: 
    libcxx/test/std/utilities/memory/specialized.algorithms/destroy.h
