  adapter: add DisableDiscoveryOnConnect option for combo chip coexistence

On systems with combo chips (shared Wi-Fi/Bluetooth antenna), background
LE scanning for auto-connect devices competes with active connections,
causing audio stuttering and Wi-Fi packet loss due to antenna
multiplexing via Packet Traffic Arbitration (PTA).

Add a DisableDiscoveryOnConnect boolean option to the [General] section
of main.conf. When enabled and an active connection exists, the option
suppresses adding devices to the kernel auto-connect list in
adapter_auto_connect_add() on kernels supporting KERNEL_CONN_CONTROL,
and gates trigger_passive_scanning() on older kernels.

The option defaults to false to preserve existing behavior.

  adapter: remove connected device from kernel accept list on connect

When DisableDiscoveryOnConnect is enabled, remove the device from the
kernel accept list once it has successfully connected. This prevents
the kernel from continuing background LE scanning for a device that
is already connected, eliminating antenna contention on combo chips
with shared Wi-Fi/Bluetooth radios.

The device is re-added to the accept list upon disconnection to
restore auto-reconnect capability.
