Extend "Template OS Windows" template by "service.discovery" LLD

Usually, when we add some new key support (especially LLD ones), we extend default templates by the new feature.
It helps zabbix users to notice such possibilities and start to use them easily.

It didn't happen for the "service.discovery" key for 3.0 in ZBXNEXT-1368, would be nice to fix that.

A global expression should be added too.
