Bootstrap/Load: Stop unnecessary queries when using the `do_parse_request` filter.

Developers of plugins and themes can use the `do_parse_request` filter to hot-wire requests and hook in early to render custom pages. However, even through these request may not need post queries and 404 lookups to be run, they run anyway. This can results in unnecessary SQL queries running on these requests. By adding a return value to the `parse_request` method of the `WP` class, these queries can now be skipped.

Fixes #10886.
