net: lwip: scale buffer pool size with TFTP block size
TFTP transfers fail when tftpblocksize is set to 8192 or larger due to
insufficient buffer resources for IP fragment reassembly.
Calculate PBUF_POOL_SIZE and IP_REASS_MAX_PBUFS dynamically based on
CONFIG_TFTP_BLOCKSIZE using IP fragmentation boundaries (1480 usable
bytes per fragment at 1500 MTU). The pool size includes headroom for
TX, ARP, and protocol overhead, while ensuring PBUF_POOL_SIZE remains
greater than IP_REASS_MAX_PBUFS as required by lwIP.
