    Enable async mode on supported targets in target_resume.
    
    Enabling async mode above the target layer removes duplicate code in
    ::resume methods of async-capable targets.  Commit 5b6d1e4fa4f
    ("Multi-target support") enabled async mode in do_target_resume after
    target_resume returns which is a step in this direction.  However,
    other callers of target_resume such as target_continue do not enable
    async mode.  Rather than enabling async mode in each of the callers
    after target_resume returns, enable async mode at the end of
    target_resume.
