boot: Use correct memory type for allocations

Browse Source 
We were using the wrong memory type when allocating pool memory. This
does not seem to cause a problem on x86, but the kernel will fail to
boot at least on ARM in QEMU.

This is caused by mixing different allocation types which ended up
breaking the kernel or EDK2 during boot services exit. Commit
2f3c3b0bee appears to fix this boot
failure because it was replacing the gnu-efi xpool_print with xasprintf
thereby unifying the allocation type.
But this same issue can also happen without this fix somehow when the
random-seed logic is in use.

Fixes: #27371
