[fdf] Switch SysSuspender to zircon transport and dedicated loop

In DFv2 the default dispatcher is shutdown after suspend is called. The
x86 board driver is suspended ahead of the platform bus driver. Thus, it
cannot use an fdf dispatcher and must use a dedicated async loop of it's
own control to listen for the callback. This also means it must no
longer use the driver transport for the SysSuspend protocol.
