Log Message:
-----------
executor: sys/linux: SYZOS: add support for AMD INVLPGA instruction

Implement the SYZOS_API_NESTED_AMD_INVLPGA primitive to execute the
INVLPGA instruction in the L1 guest.

This allows the fuzzer to target KVM's Shadow MMU and Nested Paging (NPT)
logic by invalidating TLB entries for specific ASIDs.

Also add a simple syzlang seed/regression test.
