non-aio USB read function was stuck in a loop waiting for more data
because data length parameter is always set 64 for fastbootd commands.
It should be a normal case to get less data than expected
since lengths of these commands are usually less than 64.
Add logic to check this and one more parameter to distinguish
fastbootd from general adbd case.

Test: try various fastbootd commands

Currently if the device is unplugged from host,
there is a lot of log spamming since fastbootd
does not not recognize that the device has been
disconnected and keeps trying to read/write to the
device.

Fastbootd is started by recovery, and communicates
over usb with the fastboot protocol.
Add additional fastboot commands to move in and out of
fastbootd. "fastboot reboot recovery" and "fastboot reboot fastboot"
Bug: 78793464
Test: fastboot reboot recovery, fastboot reboot fastboot
