Prepare release 0.16.0

[dnicolodi]

@rgommers Unless you have anything against it I'm going to get this out of the door in the next few days. The pending PRs will be material for 0.17.0

[rgommers]

Thanks @dnicolodi. I think that covers all the user-visible changes (outside of docs updates).

The one thing I'd consider adding is to note that the docs moved to https://mesonbuild.com/meson-python/. Worth including?

[rgommers]

Ah, and: pre-commit has a minor complaint

[rgommers]

Do you want to do this release, or do you want me to take care of it? Either way you may want to add your GPG key to docs/about.rst?

[dnicolodi]

#594 should be mentioned too, probably. I'm not sure mentioning the documentation location change in a changelog that is visible only at the new location is that useful. But I don't have anything against it.

Ah yes, agreed. There are two editable install related entries; this one is deserving of a separate mention indeed.

[dnicolodi]

If you have the time for it, I'll appreciate if you could cut the release once the last bits are committed.

[rgommers]

Sure, will do. I've been utterly swamped for too long, but I should just make time. Turning off Slack now and will keep working on meson-python for most of today:)

Thanks @rgommers! I updated the changelog, PTAL. I think there isn't anything else that we want to include in 0.16.0

[rgommers]

LGTM, in it goes.
