Added AllSiblingSystemParachains matcher to be used at a parachain level (#2422)

As suggested in this thread:
https://github.com/polkadot-fellows/runtimes/pull/87#discussion_r1400237122

We already have the `IsChildSystemParachain`, which may be used at relay
chain, but it can't be used at a parachain level. So let's use
`AllSiblingSystemParachains` for that. I was thinking about
`AllSystemParachains`, but it may cause wrong impression that it can be
used at a relay chain level.
