[PATCH v12 02/10] hvf: Add execute to dirty log permission bitmap

[Alexander Graf]

Hvf's permission bitmap during and after dirty logging does not include
the HV_MEMORY_EXEC permission. At least on Apple Silicon, this leads to
instruction faults once dirty logging was enabled.

Add the bit to make it work properly.
