Paper build system initial import into Libreboot

This is the initial import of the Paper build system into Libreboot.
It was written as a flexible and painless replacement for the Libreboot
build system, allowing to support many different configurations.
It currently only supports the following CrOS devices:
* Chromebook 13 CB5-311 (nyan big)
* Chromebook 14 (nyan blaze)
* Chromebook 11 (HiSense) (veyron jerry)
* Chromebit CS10 (veyron mickey)
* Chromebook Flip C100PA (veyron minnie)
* Chromebook C201PA (veyron speedy)

The build system also supports building various tools and provides
various scripts to ease the installation on CrOS devices.
