The existing implementation of `PlatformLocation` uses a custom URL parsing mechanism that can be brittle and doesn't properly update the `href` property. This change refactors the URL parsing to use the native `URL` constructor, providing more robust and accurate parsing of URLs, which also correctly updates the `href` property.
The tests for `PlatformLocation` have also been moved to a dedicated file to improve organization and clarity.
