threadsafe_hash_map should use hardware_destructive_interference_size for cache_line_size

[kenba]

C++ 17 introduced hardware_destructive_interference_size as the minimum offset between two objects to avoid false sharing.
This value should be used in the threadsafe_hash_map class instead of cache_line_size.

Reverted change to threadsafe_hash_map.hpp because it caused github actions build to fail see: failing run.
It appears to be because the github actions ubuntu latest compiler does not properly support C++ 17.
