Enables a combination of settings that are planned to be default in future versions of ZMK.
This includes changes to timing on BLE pairing initation, BT Secure Connection passkey entry,
and allowing overwrite of keys from previously paired hosts.
restores use of the updated/new LLCP implementation, disables 2M PHY support, and allows
overwrite of keys from previously paired hosts.
