memblock tests: update alloc_api to test memblock_alloc_raw
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. The content of the memory region is
initialized to nonzero, and we expect it to remain unchanged if running
memblock_alloc_raw().
