platform/x86/intel/vsec: allocate res with intel_vsec_dev
Use a flexible array member to combine allocations. Avoids having to
free separately.
Add __counted_by for extra runtime analysis.
Move counting variable assignment to after allocations as is already
done by kzalloc_flex for GCC 15 and above.
