Increase default ML Timeline debug buffer size and add new ML_timeline_settings.buffer_config

[IshitaGhosh]

Problem solved by the commit

1. Increase default size of ML Timeline debug buffer to capture more data without overwriting
2. Introduce ML_timeline_settings.buffer_config to accept ML Timeline debug buffer configuration with shim column, index of uC
3. Remove ML_timeline_settings.num_buffer_segments config in xrt.ini
