Is your feature request related to a problem? Please describe.

Exposure of mbarrier.arrive_tx is incomplete

Describe the solution you'd like

Add barrier<thread_scope_block>::arrive_tx member function that returns an arrival_token.

Describe alternatives you've considered

An experimental namespace that wraps this PTX instruction is unappealing because the type of arrival_token can change in the future. See issue #354

Additional context

Necessary for #38
