feat(NcActionButton): support boolean value for radio type

[ShGKme]

🏃‍♂️ Short description

Allows to have checkbox-like usage for developers having radio semantics for users.

☑️ Resolves

Currently NcActionButton[type="radio"] supports only string modelValue based on value value. For example, if we have alignment, we can use the button with one string variable with left | center | right value.

<NcActionButton :model-value.sync="align" value="left"   type="radio" />
<NcActionButton :model-value.sync="align" value="center" type="radio" />
<NcActionButton :model-value.sync="align" value="right"  type="radio" />

align = left | center | right

It is great in a general case. But sometimes it is more convenient to define boolean check value for each button. For example, in text, where the value is more complex like ['heading', { level: 1 }] and is managed by Tiptop.

Imagine, we have such a data structure and update method. So we want to define the checked state for each button as it is, not by value.

const align = {
  isLeft: false,
  isCenter: true,
  isRight: false,
}

function setAlign(direction) {
  this.align.isLeft = false
  this.align.isCenter = false
  this.align.isRight = false
  this.align[`is${direction}`] = true
},

<NcActionButton :model-value="align.isLeft"   type="radio" @update:modelValue="setAlign('Left')" />
<NcActionButton :model-value="align.isCenter" type="radio" @update:modelValue="setAlign('Center')" />
<NcActionButton :model-value="align.isRight"  type="radio" @update:modelValue="setAlign('Right')" />

This PR introduces such a feature, based on modelValue type.

@juliushaertl Am I right that in text with Tiptop it is easier to detect if a button is active like for ['heading', { level: 1 }], than to have a string value for each option?

That sounds like a sane addition. One thing I'm unsure about is switching to radio buttons in text give then current behaviour that you can toggle for example a heading style by clicking again on it. That doesn't seem like something a radio button would usually handle (unless there is an additional radio state for the paragraph style for example)

I'm not sure, I understand where I can find this behavior...

When I click on the "Heading" menu button, it always only opens the menu and doesn't change the styles, until I select the heading level.

And for disabling heading, I need to click on the selected heading.

But I realised now that click on selected radio button should probably disable the the selected item

Added toggle behavior for boolean values

[juliusknorr]

Yes, that is what I was referring to, toggling the radio state on the actual menu entries.

Might lead to situations where multiple radio buttons are active on the same time, but thats even possible now. So good for me, I like the feature!

Yes, but the same with native input[type=radio], if they have duplicated name or no name.

We probably may add some automatic grouping in future:

• Easy in NcActionsButtonGroup
• A bit complex in NcActions where many groups separated by NcActionSeparator may exist.
