Rename InputTypeView::updateInnerTextValue to updateView.

'innerText' is a component in TextFieldInputType, but the function is used for
BaseMultipleFieldsDateAndTimeInputType too. It should have an appropriate name.

Also, this CL fixes wrong calls to this function with m_inputType. It should be
m_inputTypeView because the function is a member of InputTypeView. This change
will remove unnecessary code execution in a case of author ShadowRoot attached.

Remove [Conditional] overloaded method tests

There are only 4 [Conditional] methods, none overloaded,
and these should go away soon.
Thus this test is not necessary, and we are not going to implement it
in the Python rewrite, as it adds unnecessary complexity.
