[TASK] Deprecate TSFE->ATagParams

The TypoScriptFrontendController holds a property
called "ATagParams". Its value is a copy of
$TSFE->config[config][ATagParams].

The information can be retrieved from the config array, just like
all other things are loaded there, as the usages of this property
are rather low.

In addition cObj->getTagParams' 2nd argument "addGlobal"
which is always set to true, is marked as deprecated as well.
