Allow arbitrary tag attributes in ViewHelpers

According to Feature #104223 and the update to Fluid Standalone to 2.12, since TYPO3 13.3 tag based view helpers (such as <f:image /> or <f:form.*>) can now receive arbitrary tag attributes which will be appended to the resulting HTML tag, without dedicated registration.

With this commit, all occurrences of registerTagAttribute() in ViewHelpers have now been removed in this context.

In PhpStorm, this leads to the warning This argument couldn't be found within the view helper. if one of the affected attributes is set.
