conf: add VIR_DOMAIN_CHR_SERIAL_TARGET_TYPE_SCLP

Browse Source 
Introduce specific a target types with two models for the console
devices (sclp and sclplm) used in s390 and s390x guests, so isa-serial
is no more used for them.

This makes <serial> usable on s390 and s390x guests, with at most only
a single sclpconsole and one sclplmconsole devices usable in a single
guest (due to limitations in QEMU, which will enforce already at
runtime).
