automation: arm64: Create a test job for testing static allocation on qemu

Enable CONFIG_STATIC_MEMORY in the existing arm64 build.

Create a new test job, called qemu-smoke-arm64-gcc-staticmem.

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

The test configures DOM1 with a static memory region and adds a check in the
init script.
The check consists in comparing the contents of the /proc/device-tree
memory entry with the static memory range with which DOM1 was configured.
If the memory layout is correct, a message gets printed by DOM1.

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