Device-bound session creation can now defer sending the first prompt separately

What

Session creation for device-bound sessions now supports a deferFirstPrompt flag. When set, it filters the first user event out of the events sent when the session is created.

Why

This appears to allow the first prompt to be sent separately after the session is created, rather than bundled in with session creation, though the finding doesn't specify exactly how that separate send happens.
