[BUGFIX] Use late static binding for compilable viewhelpers

Using self::renderStatic() in the render method of the viewhelpers
forces extending viewhelpers to copy the render method, which is
useless overhead.

Adjust all viewhelpers to use static::renderStatic() instead to
allow for late static binding.
