[PATCH v3] hvf: Report HV_DENIED error

[Antonio Caggiano]

On MacOS 11 and subsequent versions, in case the resulting binary is not
signed with the proper entitlement, handle and report the HV_DENIED
error.

Signed-off-by: Antonio Caggiano <quic_acaggian@quicinc.com>

v2: Use architecture specific defines from AvailabilityMacros.h to enable the
    HV_DENIED case only on MacOS 11 and subsequent versions.
v3: Fix ifdef guard.
