emulation: Use bloblist to hold tables

QEMU can have its own internal ACPI and SMBIOS tables. At present U-Boot
copies out the SMBIOS tables but points directly to the ACPI ones.

The ACPI tables are not aligned on a 4KB boundary, which means that UPL
cannot use them directly, since it uses a reserved-memory node for the
tables and that it assumed (by EDK2) to be 4KB-aligned.

On x86, QEMU provides the tables in a mapped memory region and U-Boot
makes use of these directly, thus making it difficult to use any common
code.

Adjust the logic to fit within the existing table-generation code. Use a
bloblist always and ensure that the ACPI tables is placed in an aligned
region. Set a size of 8K for QEMU. This does not actually put all the
tables in one place, for QEMU, since it currently adds a pointer to the
tables in QFW.

On ARM, enable bloblist so that SMBIOS tables can be added to the
bloblist.
