Revert to starting APs before doing the dummy runs.
...
That optimisation occasionally caused a hang if the CPU sequencing
mode was reconfigured after testing had started. It didn't make a
significant difference to the startup delay, so just drop it.

Don't attempt to start the APs when restarting after a config change.
...
Leave the APs running whilst the BSP repeats the dummy runs. This means
we need to bypass the barriers during a dummy run. The APs will wait at
the first barrier until the BSP starts the first real run.

Don't make assumptions about usable memory.
...
When using a legacy BIOS, the memory regions used by the BIOS are well
defined. This is not the case when using a UEFI BIOS. So include the
stack area in the BSS so the loader knows how much memory to allocate,
and check we have space to relocate the program to either low or high
memory.
There are still some assumptions in the USB driver code that need to
be fixed.

Don't start APs until after dummy runs have finished.
...
This should significantly improve startup time on machines with many
cores, as the barriers become no-ops during the dummy runs.

Fix operation with a subset of CPU cores enabled.
...
The last commit removed too much - there are a couple of places where
we need to use a virtual CPU number rather than a physical CPU number.

Remove distinction between physical and virtual CPUs.

This is no longer needed, now we can display as many CPUs as we can
physically handle.

Properly protect the startup stack with a mutex.
...
Because we start the APs sequentially, it is unlikely they will coincide
for the brief period that they use the temporary startup stack, but we
should guard against it. This allows us to remove the mutex around the
restart of each AP when relocating, which should improve test times.
