fix: defer when clicking hash links with data-sveltekit-reload

[teemingc]

fixes #12582
fixes #12188

Replaces #10032 by using location.replace to allow the browser to handle hash link behaviour instead #10856 (comment)

This PR ensures that clicking on a hash link with the reload option avoids the usual behaviour of thinking the page will reload and instead allows it to be handled as if the option wasn't enabled (hash links on the same page never reload the page).

It also fixes a behaviour where an element doesn't get focused when clicking on the hash link more than once.

TODO:

• fix behaviour where clicking a hash link twice doesn't focus the input
