fix(aarch64): add support od macOS HVF on Apple Silicon

[stlankes]

This series makes Hermit's aarch64 kernel boot under macOS HVF on Apple Silicon, in addition to the existing TCG support. Three small adjustments are needed: virtual timer instead of physical, PSCI shutdown instead of semihosting, and FEAT_PAN-aware EL1 setup.
