executor: sys/linux: SYZOS: add support for AMD Nested Event Injection
Implement SYZOS_API_NESTED_AMD_INJECT_EVENT to allow the L1 guest to
inject events (Interrupts, NMIs, Exceptions) into L2 via the VMCB EVENTINJ
field.
This primitive abstracts the VMCB bit-packing logic
(Vector, Type, Valid, Error Code) into a high-level API, enabling the fuzzer
to semantically mutate event injection parameters.
This targets KVM's nested event merging logic, specifically where L0 must
reconcile L1-injected events with Host-pending events.
