[nrf fromtree] west: linkserver: change the default port number for semihost

LinkServer manages port numbers for gdb and semihost as separate linear
sequences when invoked to debug multi-core applications, e.g the
gdb-server instance for cpu0 will have the default GDB port 3333 and the
next gdb-server instance will be assigned the port 3334. The latter will
conflict with the default port for semihost which is 3334.

This patch changes the default port for semihost to 8888.
Port numbers can be changed when invoking the linkserver runner.
