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

ESP-IDF BT-INQUIRY demo
======================

Demo of Classic Bluetooth Device and Service Discovery

This is the demo for user to use ESP_APIs to perform inquiry to search for a target device and then performs service search via SDP.

Options choose step:
    1. make menuconfig.
    2. enter menuconfig "Component config", choose "Bluetooth"
    3. enter menu Bluetooth, choose "Classic Bluetooth" and do not choose "Release DRAM from Classic BT controller"
    4. choose your options.

After the program started, the device will start inquiry to search for a device with Major device type "PHONE" in the Class of Device Field. Then it will cancel the inquiry and started to perform service discovering on this remote device.
