Bluetooth: HCI: Add HCI_QUIRK_BROKEN_ENHANCED_SETUP_SYNC_CONN quirk
This adds HCI_QUIRK_BROKEN_ENHANCED_SETUP_SYNC_CONN quirk which can be
used to mark HCI_Enhanced_Setup_Synchronous_Connection as broken even
if its support command bit are set since some controller report it as
supported but the command don't work properly with some configurations
(e.g. BT_VOICE_TRANSPARENT/mSBC).
