init.rc: Set TCP memory size

Browse source 
Set ipv4 min/default/max write and read memory size and socket max send/receive memory size to values that are high enough to reach 1+Gbps over wifi and cellular. Moving forward there is no need to override them in per device init.rc or framework config file.

Bug: 213596972
Test: manual test to confirm TCP memory size is increased and wifi TCP throughput with default TCP window size can reach 700Mbps in HE80 mode.
