[HxInputText] Optional Text Selection on Focus

[TPIvan]

I've noticed that in HxInputNumber, when the input field receives focus, all the text within is automatically selected. This is facilitated by the following line in BuildRenderInput:

 builder.AddAttribute(1002, "onfocus", "this.select();");

I find this feature quite useful and was wondering if it could be implemented as an optional behavior for HxInputText as well. Having the ability to enable or disable this auto-selection on focus would be a great enhancement for user experience.

Is there a possibility to introduce this feature? I can prepare pull request if approved.
