Hi,

This patch is a very compressed version of Daniel's. Originally, it
performed code motion between dom0_build.c and domain-builder/domain.c,
but in order for this to go in early, I've compressed everything in a
single hunk and left it in dom0_build.c.

We can move whatever must be moved later on.

I could see inlining the affinity settings and removing this function
altogether (having a regular vcpu_create() in its place). I've kept it
as is for consistency with the previous patch.

See https://lore.kernel.org/xen-devel/20250515131744.3843-5-dpsmith@apertussolutions.com/

I've kept the S-by too, as this patch descends directly from that one.

Differences with Daniel's RFC:
  * Function takes a domain, as the struct already exists by then.
  * Apply dom0 cmdline overrides to control and hardware domains.
  * Keep everything in dom0_build.c for the time being.
  * Remove arm's incarnation of the function. It's just useless.

Cheers,
Alejandro
