Add autofocus to button element

[quranc]

Describe the feature you would like to see added

Similar to how other existing components (Dropdown, InputMask, AutoComplete) are possible to have a autofocus property, this could also be a property to the button element.
This can today be done by using angular directives.

Is your feature request related to a problem?

Instead of having to make a new class/file, this could instead be done by just adding a single attribute to the element.

Describe the solution you'd like

Autofocus enabled:
<p-button [autofocus]="true"></p-button>

Autofocus disabled:
<p-button [autofocus]="false"></p-button>
<p-button></p-button>

Describe alternatives you have considered

New file/class with autodirectives

Additional context

Should not be too much work since this is already implemented in other primeng components.

Hi,

Since this problem occurs across many components, I'm closing this issue and merging them into one #11807. We'll fix them altogether.

Thanks for your support and report!
