Oniro close up: Technical Architecture, Yocto-based build system, build flavours

We introduce you to the Yocto (OpenEmbedded) build system and the way Oniro uses it to build for different "flavours" like Linux, Zephyr and other RTOS systems. From an overview of the meta layer collection, we will dive into Oniro specific features like a read-only root filesystem and unified kernel tree over a range of supported boards.

In the last part, we will run through the needed steps to enable a new board for Oniro.
