Cross Platform Action 1.4.0

Added

• Add support for FreeBSD on RISC-V 64 (riscv64) (#36)
• Add support for NetBSD on VAX, running on the SIMH simulator
• Add support for NetBSD 11.0 (#154)

Changed

• OpenBSD on ARM64 now boots with the same EDK II UEFI firmware (uefi.fd) as
  every other ARM64 guest, instead of a separate Linaro UEFI build. The QEMU
  machine type for OpenBSD on ARM64 is now virt,acpi=off, which makes the
  kernel fall back to the device tree instead of hanging during ACPI attach.
  This removes the dependency on the Linaro release server, which no longer
  exists

Fixed

• Don't log the Tearing down VM group when shutdown_vm is false, since
  the VM is not being torn down in that case
  (#109)
• The "Start VM" step could keep running for hours when the VM failed to boot
  (#158).
  Waiting for the VM to become ready is now bounded by an actual wall clock
  timeout, instead of by a number of connection attempts, and a single SSH
  connection attempt is bounded by ConnectTimeout.
• The post job step now reports when the console log of the VM is missing or
  empty, instead of silently printing nothing
  (#158)
• A reboot of a guest that dies instead of rebooting now fails after roughly
  20 seconds, instead of after 13 minutes. The SSH session that issues the
  reboot is bounded by ServerAliveInterval, so it no longer blocks for the
  full TCP retransmission time, and waiting for the VM to come back up is
  given up on as soon as the guest announces a kernel panic on its serial
  console
• Advanced Matrix Extensions (AMX) is no longer exposed to the guests on
  x86-64, so which runner a job happens to get no longer decides whether the
  VM boots
  (#158).
  Kernels released before AMX existed fault as soon as userland starts, which
  affected NetBSD 9.4 and 10.1 and FreeBSD 12.4 on the runners that have it
