string: Make tests birdirectional test-memcpy.c
Add tests that had src/dst non 4-byte aligned. Since src/dst are
initialized/compared as uint32_t type which is 4-byte aligned this can
break on some targets.
Fix the issue by specifying a new non-aligned 4-byte
`unaligned_uint32_t` for src/dst.
Another alternative is to rely on memcpy/memcmp for
initializing/testing src/dst. Using memcpy for initializing in memcpy
tests, however, could lead to future bugs.
