A clear icon for the Date Picker

[bretto36]

When using the Date Picker on a mobile device (ios) using the non native date picker, if you have a default value there is no way to clear the value afterwards.

I'd love to introduce the ability to clear the field, i've been able to implement it using an Action but it's less elegant and results in a request to clear the value. Having it native to the js and using a method like ->clearable(true/false) would be super useful

I've checked the latest v5 code and can't see that it's been added so adding a discussion for it. I'd try and help but the package structure really makes contributing tricky
