feat: add webdriver options for windows

[thewh1teagle]

Add option to pass webviewOptions into tauri web driver,
As per capabilities-edge-options#webviewoptions-object

When testing with webdriver, I needed to use the default data directory of my app for authentication,
and the only way to pass it with webview2 is using webviewOptions.

Usage example:

const capabilities = new Capabilities();
capabilities.set("tauri:options", {
    application,
    args: [], // passed to EdgeOptions
    webview_options: {
	    additionalBrowserArguments: ["--user-data-dir=C:\Users\User\AppData\Local\AppName\EBWebView"],
    },
});
capabilities.setBrowserName("wry");

// start the webdriver client
driver = await new Builder()
  .withCapabilities(capabilities)
  .usingServer("http://127.0.0.1:4444/")
  .build();
