Add a number of steps and details that were not called
out in the "Getting Started Guide for ACRN Hybrid Mode". Those
are not obvious to the first-time or novice user so the user
guide was hard to follow and confusing. At a high-level:
* How to build Zephyr
* How to install ACRN
* How to install the ACRN kernel
The hybrid scenario overview diagram has been updated too.
