bt-kernel: Additional bazel configuration

- add support to copy *.ko to out dir
- enable conditional compilation with config flags
- enable CONFIG_BT_HW_SECURE_DISABLE with dependency on securemsm-kernel
- re-enable compilation of bt_fm_slim with new headers
- add fallthrough attribute btfm_slim_hw_interface.c
- move BTFMSLIM_DEV_NAME to btfm_slim.h
- add target.bzl file to define specific targets
