FF145 Experimental Features: Idempotency-Key

[hamishwillee]

FF135 added support for the Idempotency-Key header behind a preference - I'm working on this because there was an abortive attempt to ship in 145.

This adds an experimental feature record. There is no point adding a release note back for FF135.

Related docs work can be tracked in #41497
