Deprecate the spaceless filter
Closes #3576
Deprecate the `spaceless` filter for the following reasons:
* The performance is bad (as the work is done at runtime via a regexp)
* Optimizing the size of an HTML doc server side is "almost never" a good idea (compression is better and enough)
* There are some edge cases where you want to keep some spaces (see #3576)
* Controlling whitespace is possible and fine-grained via the dedicated Twig modifiers on `{{ }}`
If someone find it useful, re-creating it is trivial (`return trim(preg_replace('/>\s+</', '><', $content ?? ''));`),
but with so many caveats and not so many use cases, I think it does not belong to core.
