executor: sys/linux: implement SYZOS_API_NESTED_VMLAUNCH
Provide a SYZOS API command to launch the L2 VM using the
VMLAUNCH (Intel) or VMRUN (AMD) instruction.
For testing purposes, each L2->L1 exit is followed by a guest_uexit_l2()
returning the exit code to L0. Common exit reasons (like HLT) will be
mapped into a common exit code space (0xe2e20000 | reason), so that
a single test can be used for both Intel and AMD.
Vendor-specific exit codes will be returned using the 0xe2110000 mask
for Intel and 0xe2aa0000 for AMD.
