selftests: KVM: aarch64: Introduce hypercall ABI test

Browse source

Introduce a KVM selftest to check the hypercall interface
for arm64 platforms. The test validates the user-space'
[GET|SET]_ONE_REG interface to read/write the psuedo-firmware
registers as well as its effects on the guest upon certain
configurations.
