Breaking: #60135 - Recursive stdWrap is now only called once

See Issue #60135

Description

If recursive stdWrap configuration was used, the stdWrap method was called twice, although the content was only rendered once. This performance overhead is now removed.

Impact

If a recursive stdWrap configuration is used, which sets or acts on a global state like registers, the resulting rendering can now be different because the global state is now modified only once.

Affected installations

A TYPO3 instance is affected if there is TypoScript code like:

page.1 = TEXT
page.1 {
  value = Counter:
  append = TEXT
  append.data = register:Counter
  stdWrap.append = LOAD_REGISTER
  stdWrap.append {
    Counter.cObject = TEXT
    Counter.cObject.data = register:Counter
    Counter.cObject.wrap = |+1
    Counter.prioriCalc = 1
  }
}

This now correctly outputs Counter:1 instead of Counter:2

Migration

The usage of recursive stdWrap TypoScript configuration needs to be checked and probably adapted to fit the fixed behavior.
