[kernel][arm64] Disable EL2 monitor and virtualization tests

Doing so is the plan of record, enabling a more straightforward rollout
for physboot to load the kernel at its ultimate virtual address at EL1.
In particular, this in effect disables our arm64 kernel hypervisor (to
eventually be re-enabled more simply to rely on ARM's EL2 host feature).

We replace the `arm64_elX_to_el1()` routine with a phys-friendly
`arch::ArmDropToEl1WithoutEl2Monitor()`, as we'll soon call this in
physboot as well.
