HTML API: Fix extensibility of WP_HTML_Processor::next_token().

Browse Source 
Break out logic from the `next_token()` method into a private method which may call itself recursively. This allows for subclasses to override the `next_token()` method and be assured that each call to `next_token()` corresponds with the consumption of one single token. This also parallels how `WP_HTML_Tag_Processor::next_token()` wraps a private `base_class_next_token()` method.

Props westonruter, jonsurrell.
Fixes #62269.
