add dynamic stacksize for procBLETask

[Lukaswnd]

add OVERRIDE_PROC_BLE_TASK_STACK_SIZE to set the stacksize for the procBLETask by a define in the build_flags

Description:

When using the ESP32s3-devkit-c1 with Arduino and using it as a ble gateway, the task watchdog for the stacksize gets triggerd, if you receive a request the same time it scans for new devices. This results in a crash. I testes it with 13500 and it works fine. I think a build flag which each user can set seperatly but doesn't have to is the best option to solve it.

Checklist:

• The pull request is done against the latest development branch
• Only one feature/fix was added per PR and the code change compiles without warnings
• I accept the DCO.

Would be interesting to adjust the stack size from the 8500 low limit, I would prefer to increase this one rather than going directly to the 13500.

If you put the log level to trace you will have a view of how much stack is remaining at the end of the scan. You may want to add other trace but this first log should give you an idea.
