[PATCH v2 2/2] automation: arm64: Create test jobs for testing static shared memory on qemu

["jiamei.xie" <jiamei.xie@arm.com>]

Create 2 new test jobs, called qemu-smoke-dom0less-arm64-gcc-static-shared-mem
and qemu-smoke-dom0less-arm64-gcc-debug-static-shared-mem.

Adjust qemu-smoke-dom0less-arm64.sh script to accomodate the static
shared memory test as a new test variant. The test variant is determined
based on the first argument passed to the script. For testing static
shared memory, the argument is 'static-shared-mem'.

The test configures two dom0less DOMUs with a static shared memory
region and adds a check in the init script.

The check consists in comparing the contents of the /proc/device-tree/reserved-memory
xen-shmem entry with the static shared memory range and id with which
DOMUs were configured. If the memory layout is correct, a message gets
printed by DOMU.

At the end of the qemu run, the script searches for the specific message
in the logs and fails if not found.

Changes from v1:
 - Move the second domU creation to the general ImageBuilder script.
