optimize ZSTDMT_compress() memory usage

when there is enough room in dstBuffer to decompress directly there.
(previous method would skip that for 1st chunk only).

Changed memory strategy to __packed for gcc
...
Method 1 __packed is always as good or better than memcpy().
But it's not portable, as it depends on compiler extension.
For gcc, __pakced directive works fine.
Furthermore, gcc has serious performance issues with memcpy() on ARM 32 bits.
