Add a way to kill the running process of a terminal

[Totalus]

Is your feature request related to a problem? Please describe.

I sometimes run a command that I am unable to stop, even with Ctrl+C multiple times, it just keeps running. The only way I can stop it is to close the terminal running the process.

Describe the solution you'd like

I would like to be able to force kill the process running in a terminal without having to close my tab and open a new one.

Describe alternatives you've considered

In #6653 I suggested to use a Restart tab feature as a potential solution. I realized lately that it does not properly solve the problem because of two reasons:

• There can be more than one terminal in the same tab, not all of them need to be restarted.
• The restart process does not keep the environment intact and it becomes quickly annoying to have to reconfigure the environment if we need to use the Restart feature often.

My suggestion

I suggest to implemented a Kill process option in the terminal's context menu. The option would force kill the running process of the selected terminal only and keep the context and the environment variables intact.
