fastboot: Automatically reboot to userspace fastboot.
In order to flash logical partitions, "flashall" must be run against
userspace fastboot. When the bootloader supports the "reboot-fastboot"
command, we now attempt to automatically reboot into userspace fastboot.
We do this by closing the transport, sleeping for one second, and then
polling for a new connection until one is available. FastBootDriver is
then assigned the new transport.
Bug: 78793464
Test: fastboot flashall on device with logical partitions, while booted
into bootloader fastboot
