Introduce a helper returning a parser state depending on the element stack and building on that, a helper which returns the code snippet to append to. This is used for character handling and <insert-template>. It also allows for removing StackElement::InjectCodeInFunction, which was a fake element for remembering that the code injection targets a function. Also, add all type entry code snippets directly to the type entry instead of temporarily storing them in StackElementContext::codeSnips. Use the latter for conversions only and rename it accordingly.
