[Feature request] Add code-runner.clearPrevious for terminal tab

[Cyberavater]

So, we have "code-runner.clearPreviousOutput": true, which is nice if the code is running on the output tab, but if the user is using "code-runner.runInTerminal": true, (i.e. running the code on the terminal tab) this is not much useful. So, please add a corresponding setting for terminal windows as well.

Hey I also faced exactly same problem, the terminal becomes glitchy and in the end fails.
Here I have explained in detail with an example.
Please fix this asap as it is an important feature.

when"code-runner.runInTerminal": true, "code-runner.clearPreviousOutput": true works on macOS(I think Linux too), but on windows, it has problem, please fix it.
