aisingapore#466 / aisingapore#417 - shell script to kill TagUI processes

Follow-up update to previous 2 commits below -

Making a commit to improve on the existing script to kill TagUI processes.

For eg if Ctrl+C is used to kill TagUI prematurely, TagUI main process would lose the control to do clean-up of integrations (SikuliX, R, Python, Chrome) and Chrome browser.

This shell script (for all the 3 OSes) will kill those processes to free up memory and allows TagUI to start running from a clean state.

These actions are not done by default when TagUI is launched, as it is expected that TagUI exits cleanly. Otherwise cleaning up all processes by default will hide potential issues should they arise and they will end up not getting reported.
