[media] Preserve native device formatting when sanitizing AirPods names

When sanitizing AirPods device names to remove PII, the existing logic
aggressively removed native Windows formatting such as "Headphones",
"Headset", and "(Bluetooth)".

This CL updates RedactDeviceName to preserve these form factor prefixes
and connection type suffixes around the sanitized name. It also adds
support for preserving the shorter "Hands-Free" profile variant
alongside the existing "Hands-Free AG Audio".

This functionality is inline with how it works for other standard BT
devices where the (Bluetooth) suffix is not removed.
