gdb: add maybe_switch_inferior function
Add the maybe_switch_inferior function, which ensures that the given
inferior is the current one. Return an instantiated
scoped_restore_current_thread object only we actually needed to switch
inferior.
Returning a scoped_restore_current_thread requires it to be
move-constructible, so give it a move constructor.
