Optimize or release memory in bluetooth

1. add option to release about 30K from BT if BLE only
2. later BT/BLE will be separated by BT/BLE macro, but this option should use when user make sure that in BLE only mode.

This option should only be used when BLE only.
Open this option will release about 30K DRAM from Classic BT.
The released DRAM will be used as system heap memory.
