Rename CFFL_RadioButton::GetRadioButton() to GetPWLRadioButton()

Straight rename, no funny business.

I spent a few seconds wondering why we had to call GetRadioButton() on
a CFFL_RadioButton and whether it was superfluous and should be removed.
It's not, since it returns an object from the lower PWL layer. The
new naming should make this more obvious.

-- Do the same for CFFL_CheckBox, CFFL_ListBox, and CFFL_TextField.
