Add collectives-westend and glutton-westend runtimes (#2024)

Add collectives and glutton parachain westend runtimes to prepare for
#1737.

The removal of system parachain native runtimes #1737 is blocked until
chainspecs and runtime APIs can be dealt with cleanly (merge of #1256
and follow up PRs).

In the meantime, these additions are ready to be merged to `master`, so
I have separated them out into this PR.

Also marked `bridge-hub-westend` as unimplemented in line with [this
issue](https://github.com/paritytech/parity-bridges-common/issues/2602).

TODO
- [x] add to `command-bot` benchmarks
- [x] add to `command-bot-scripts` benchmarks
- [x] generate weights
