feat: add commandLine.removeSwitch

[MarshallOfSound]

In some cases apps may want to remove Chromium command line switches to avoid certain Chromium behaviors being used, E.g. remote-debugging-port or gpu-launcher

Notes: Added commandLine.removeSwitch to allow apps to remove command line switches from Chromiums internal command line representation

API LGTM but you forgot a line in app.ts

electron/lib/browser/api/app.ts

Lines 37 to 44 in 93068cf

	Object.assign(app, {
	commandLine: {
	hasSwitch: (theSwitch: string) => commandLine.hasSwitch(String(theSwitch)),
	getSwitchValue: (theSwitch: string) => commandLine.getSwitchValue(String(theSwitch)),
	appendSwitch: (theSwitch: string, value?: string) => commandLine.appendSwitch(String(theSwitch), typeof value === 'undefined' ? value : String(value)),
	appendArgument: (arg: string) => commandLine.appendArgument(String(arg))
	} as Electron.CommandLine
	});
