[Forms] Move isKeyboardFocusable and isMouseFocusable to InputType from HTMLInputElement

For introducing time fields UI and code cleanup, input type class should decide of keyboard/mouse focus-able rather than HTMLInputElement.

== Current ==
bool HTMLInputElement::isKeyboardFocusable(KeyboardEvent* event) const
{
    if (isTextField())
        return HTMLTextFormControlElement::isFocusable();
    return HTMLTextFormControlElement::isKeyboardFocusable(event) && m_inputType->isKeyboardFocusable();
}

== Proposed ==

bool HTMLInputElement::isKeyboardFocusable(KeyboardEvent* event) const
{
    return m_inputType->isKeyboardFocusable(event);
}

bool InputType::isKeyboardFocusable(KeyboardEvent* event) const
{
    return element()->isTextFormControlKeyboardFocusable(event); // call new method in HTMLInputElement class
}

bool TextFieldInputType::isKeyboardFocusable(KeyboardEvent* event) const
{
    return element()->isTextFormControlFocusable(); // call new method in HTMLInputElement class
}

They shouldn't be virtual.
Also, please put them just below setValueInternal() because it is also a helper for *InputType.

if (!InputType::isKeyboardFocusable(event))
is better.
