[Feature Request]: Automatic platform detection. (VSC-1580)

[SinglWolf]

Greetings!
There are a lot of similar lines in the vscode-esp-idf-extension settings that confuse beginners and greatly annoy more experienced users (e.g., me)

Using the example of typescript, I propose a solution to the problem with different delimiters in the path, depending on the platform on which vscode-esp-idf-extension is running.

import * as os from 'os';

const platform = os.platform();

if ((platform === "linux") || (platform === "darwin")){
    // linux or OS X
   // e.g.
    SLASH = '/';
}else if (platform === "win32"){
    // Windows...
   // e.g.
    SLASH = '\\';
}

This will allow to show only the necessary elements in the vscode-esp-idf-extension settings.
