Dennis Klein c28da54381 feat(ofi): Require asiofi 0.5
* Modernize some ofi transport code along the way
  * Replace Boost.Container with `<memory_resource>`
  * Introduce namespaced headers
    * `<fairmq/Channel.h>`
    * `<fairmq/Message.h>`
    * `<fairmq/Poller.h>`
    * `<fairmq/Socket.h>`
    * `<fairmq/TransportFactory.h>`
    * `<fairmq/UnmanagedRegion.h>`
* Compile-firewall Boost.Process in `shmem::Manager` because it conflicts
with standalone asio
