tcp: switch tcpflags_t to u16_t for all cases (bug #51326)

Browse Source 
This changes tcpflags_t to be a u16_t for all cases.  The TCP Appropriate
Byte Count support added a new flag that used a bit past 8 and since this
flag is now required, tcpflags_t can no longer be a u8_t

This does not increase the size of struct tcp_pcb due to padding that
already existed (see bug #51326 for details)
