Tian Hao ee787085f9 component/bt : decrease memory consumption by conn number
1. BLE only with 9(max) connection will decrease 3K DRAM
2. BR/EDR only with 7(max) connection will decrease 16K DRAM
3. Any of BLE or BR/EDR connection number decrease will also decrease DRAM consumption
4. Decrease one BLE connection will save about 1KB DRAM
5. Decrease one BR/EDR ACL connection will save about 1.2KB DRAM
6. Decrease one BR/EDR SCO/eSCO will save 2KB DRAM.
7. fix some definition and kconfig
8. remove 1.2k of vhci tx cache and make .bss & .data to heap about 1.4K
9. modify BT Reserved Memory size and modify example to support new bt kconfig
