Coin: Run VxWorks QEMU autotests against parallel emulators

Boot several VxWorks QEMU instances per host and drive them
concurrently instead of running every autotest serially against a
single emulator. A 2x2 trial (2 instances, 2 cores each) already
halved the ARM autotest wall-clock time, so scale the launcher to an
arbitrary instance count.

vxworks_qemu_launcher.sh now takes an optional instance id and gives
each instance its own tap device, guest IP (172.31.1.10+N), MAC,
serial FIFO pair and QEMU log. Instance 0 keeps the previous addresses
so a single-instance run is unchanged. The shared bridge/tap setup is
serialized with flock and made idempotent so parallel launches do not
race on it. The SSH readiness probe targets the instance's own IP.

Emulator sizing:
- Intel: 4 instances, -smp 4 -m 4G each (KVM).
- ARM: 2 instances, -smp 2 -m 2G each (TCG).

Bump the x86_64 test configuration from VMSize8 to VMSize16 so the
host can accommodate 4 instances x 4 cores / 4 GB. ARM stays on
VMSize8 (2 x 2 cores).

Set VxWorks QtBase tests insignificant till all the problems are fixed

Upgrade to VxWorks 26.03, needs several fixes, which depend on each
other. But they fail on staging, because they are not staged together.
After the changes are in dev and 6.12 branch, the test insignificant
feature can be removed.
