Update memblock_alloc() tests so that they test either memblock_alloc()
or memblock_alloc_raw() depending on the value of alloc_test_flags. Run
through all the existing tests in memblock_alloc_api twice: once for
memblock_alloc() and once for memblock_alloc_raw().

When the tests run memblock_alloc(), they test that the entire memory
region is zero. When the tests run memblock_alloc_raw(), they test that
the entire memory region is nonzero.
