Corrected bugs with cursor in TextField

[1scaR1]

1. Fixed bug in ccui TextFiled with cursor, when secure input enabled (if enable secure text entry and cursor, it will not be show)
2. Fixed bug in TextFiledTTF with setting placeholder text when field is empty and keyboard attached(this leads to displaying placeholder text && incorrect cursor positioning), code example:

    auto input = cocos2d::ui::TextField::create();
    
    input->addEventListener([=](Ref* sender, Ref*, cocos2d::ui::TextField::EventType type) {
        if(type == cocos2d::ui::TextField::EventType::ATTACH_WITH_IME)
            input->setPlaceHolder("Some string");
    });

Fixed bug in ccui TextFiled with cursor, when secure input enabled (if enable secure text entry and cursor, it will not be show)

Could you please paste some codes to reproduce it?

[1scaR1]

auto textField = cocos2d::ui::TextField::create("input password here","fonts/arial.ttf",30); //font from your cpp-test resources
textField->setPasswordEnabled(true);
textField->setCursorEnabled(true);
this->addChild(textField);

Enter some text in TextField, and cursor disappears.

I have verified issue 1, but i don't quite understand issue 2(Fixed bug in TextFiledTTF with setting placeholder text when field is empty and keyboard attached(this leads to displaying placeholder text && incorrect cursor positioning), code example:). Could you please describe it in more detail about what's the issue?

I have the code like this:

auto input = cocos2d::ui::TextField::create("paceholder", "my_font_name", 20);
input-> setCursorEnabled(true);    
input->addEventListener([=](Ref* sender, Ref*, cocos2d::ui::TextField::EventType type) {
    if(type == cocos2d::ui::TextField::EventType::ATTACH_WITH_IME)
           input->setPlaceHolder("Some string");
});

State before pressing the text field(It's empty)

And state after pressing the text field(Letter "o" also blinking, instead of cursor)

I except that after pressing, text field must become empty(because of cursor)
