Fixes for data types, cast warnings and shift operations when using 16-bit platform. Added new --enable-16bit build option, which defines WC_16BIT_CPU. Fix build error when using WOLFSSL_LEANPSK and NO_WOLFSSL_MEMORY.

Tested using `avr-gcc` version 8.3.0 with: `./configure --host=avr --enable-16bit --disable-filesystem --enable-singlethreaded CFLAGS="-DWOLFSSL_GENSEED_FORTEST -DWOLFSSL_USER_CURRTIME -DWOLFSSL_USER_IO -DWOLFSSL_NO_SOCK -DNO_WRITEV -DUSER_TICKS" --enable-tls13 --enable-compkey --enable-certgen --enable-certext --enable-keygen --enable-session-ticket --enable-maxfragment`. Also with `--enable-fastmath`.
