[SystemZ] TableGen-erate node descriptions (#168113)

This allows SDNodes to be validated against their expected type profiles
and reduces the number of changes required to add a new node.

There is only one node that is missing a description -- `GET_CCMASK`,
others were successfully imported.

Part of #119709.

Pull Request: #168113
