Move HTTP client docs from components to guides

The component docs are actually very similar to the framework guide :). The biggest update is adding framework config examples to all examples showing global configuration and moving the framework integration section more to the start of the article.

We once added `php-standalone` and `php-symfony` tabs to the configuration blocks, which allow showing the same code for standalone and in-framework usage. This currently is used only in the Form component docs: https://symfony.com/doc/current/components/form.html#creating-a-simple-form I heavily used this in the article, so we can show both code examples in a concise matter.

Please let me know what you think! :)
