Felix Arntz de505f0eac Formatting: Improve performance of esc_url(). ...

This changeset indirectly improves performance of the commonly used `esc_url()` function by optimizing the low-level function `wp_kses_bad_protocol()` for the by far most common scenarios, which are URLs using either the `http` or `https` protocol.

For this common scenario, the changeset now avoids the `do while` loop. While for a single call to the `esc_url()` function the performance wins are negligible, given that `esc_url()` is often called many times in one page load, they can add up, making this a worthwhile improvement.

Fixes #22951.
