test: Add arm64_high_addresses test

Latel we have had several failures and regressions due to the setting of
CONFIG_SRAM_BASE_ADDRESS to really high values (over the 4GB boundary).
To try to catch these problems as early as possible we add a build-only
test based on the hello_world_user sample that tries to compile the test
using a combination of CONFIG_SRAM_BASE_ADDRESS and
CONFIG_KERNEL_VM_BASE set to high values in memory.
