fastboot: Add 'stage' command
(cherry-picked from internal nyc-iot-dev to AOSP)
New user-level command usage:
* fastboot stage <infile>
Sends the contents of <infile> to the device to stage for use in the
next command.
This enables OEM commands to use data downloaded from host to device.
Bug: 35811075
Test: Manual test on imx6ul
Change-Id: I483a18f9f4205d3289ee524656b9d741b16e9fe6
(cherry-picked from commit 001c75c6c0fe6a70a1db2a65253ab3c43ec17d46)
