x86/sev: Use boot SVSM CA for all startup and init code
To avoid having to reason about whether or not to use the per-CPU SVSM calling
area when running startup and init code on the boot CPU, reuse the boot SVSM
calling area as the per-CPU area for the BSP.
Thus, remove the need to make the per-CPU variables and associated state in
sev_cfg accessible to the startup code once confined.
