vasilito 0de981031c syscall: add AcpiVerb::SetS3WakingVector and AcpiVerb::EnterS3 (Phase II.X.W)

Phase II.X.W: extend the AcpiVerb enum with two new variants
for the S3 round-trip:

* AcpiVerb::SetS3WakingVector (= 5): acpid writes the
  kernel's S3 resume trampoline address to FACS.
  Mirrors Linux 7.1's acpi_set_firmware_waking_vector.
  The 8-byte write payload is the address in
  little-endian. A zero payload is a sentinel for 'use the
  kernel's default trampoline address' (s3_trampoline
  symbol).
* AcpiVerb::EnterS3 (= 6): acpid requests the kernel to
  enter S3. The kernel's stop::enter_s3() reads the
  SLP_TYP value from S3_SLP_TYP and does the PM1 register
  write. The actual S3 entry happens via acpid writing
  to /scheme/sys/kstop.

Hardware-agnostic: works on any x86_64 system with
standard ACPI S3 support (Dell, HP, Lenovo, LG Gram 14).
On Modern Standby-only systems (LG Gram 16 (2025)), the
kernel never enters S3 so these verbs are no-ops.
