Rewrite Spinner

[cagataycivici]

Current implementation is not aligned with PrimeFaces and PrimeReact, align the component behavior with the other two which uses blur event to parse the value from string to a number, current spinner does on it on keyup which causes various issues like 5490.

Hmmm. This change is backward incompatible as it removes thousandSeparator and decimalSeparator (which were actually the only features why I have used this component).

Also, documentation hasn't been changed to reflect these changes – it still contains thousandSeparator and decimalSeparator in the list of properties, without any note about them being not supported anymore
https://www.primefaces.org/primeng/#/spinner

IMO changes like this should be made in major versions only. Also there should be some information about backward incompatible changes like this in the official announcemenent or changelog. Information about this change isn't even googleable :(

Do not like it :(
