automation: Add a static memory allocation test on arm32

Add a new test job qemu-smoke-dom0less-arm32-gcc-staticmem in debug
and non-debug variant that will execute qemu-smoke-dom0less-arm32.sh
script to test static memory allocation feature. The test case itself
is directly taken from dom0less arm64 testing.

Populate build jobs to compile Xen with config options necessary to
enable static memory feature. Populate test jobs passing "static-mem"
as a test variant. The test configures domU with a static memory region
(direct-mapped) and adds a check using /proc/iomem to determine the
memory region marked as "System RAM".
