Add layer to support Jailhouse hypervisorjellyfish_9.99.2jellyfish/9.99.29.99.2
Jailhouse is a partitioning hypervisor based on Linux. It is able to run
bare-metal applications or (adapted) operating systems besides Linux.
For this purpose, it configures CPU and device virtualization features
of the hardware platform in a way that none of these domains, called
"cells" here, can interfere with each other in an unacceptable way.
This layer adds the Jailhouse package into AGL and also appends the BSPs
to allow it to run. Currently, Raspberry Pi 4 and QEMU x86-64 targets
are supported.
To enable Jailhouse and include it in the image, the AGL feature
agl-jailhouse must be enabled.
