feat(web-analytics): Add flag to send server hash instead of distinct id

[robbie-c]

Changes

Part of PostHog/posthog#25117
Main repo PR (currently WIP, this PR can be merged before that one) PostHog/posthog#25915

Everything is behind a config option with a dire warning, so this doesn't need to be final.

Checklist

• Tests for new code (see advice on the tests we use)
• Accounted for the impact of any changes across different browsers
• Accounted for backwards compatibility of any changes (no breaking changes in posthog-js!)

Idea for the future: store this kind of cross-repo setting in a global store to avoid them getting out of sync
