feat(@capacitor/bowser) Add option to clear all website data while closing iOS browser window

[GeroldSchierholz]

User Story:

After using the browser window for e.g. oauth login, I would like to have the possibility to clear all website data to ensure that a new login is not using any cookie data and logging me in again.

Description:

Optional config to clear all website data during browser.close.

@GeroldSchierholz nice! Out of curiosity, is it possible to add this as a method we can call programmatically whenever or does the browser have to be open? I was thinking it might be useful to clear the data without requiring the browser window to be open e.g. when hitting a sign-out button in an app.

If you wanted you could then programmatically call it on the browserFinished event to achieve the same functionality.
