tests/unit/test-smp-parse: Test the full 7-levels topology hierarchy
Currently, -smp supports up to 7-levels topology hierarchy:
-drawers/books/sockets/dies/clusters/cores/threads.
Though no machine supports all these 7 levels yet, these 7 levels have
the strict containment relationship and together form the generic CPU
topology representation of QEMU.
Also, note that the maxcpus is calculated by multiplying all 7 levels:
maxcpus = drawers * books * sockets * dies * clusters *
cores * threads.
To cover this code path, it is necessary to test the full topology case
(with all 7 levels). This also helps to avoid introducing new issues by
further expanding the CPU topology in the future.
