Subject: [PATCH] component/bt: add constraint in Kconfig to enable SMP_ENABLE
 when using classic BT

1. For now, some security related functions used in classic Bluetooth are controlled by "SMP_ENABLE". This commit fixes the dependency.
2. The two options, "CLASSIC_BT_ENABLED" and "SMP_ENABLED" The two options will be decoupled in the future.
