Fileupload and autocomplete: problems with input transform function

[Kue2]

Describe the bug

Since PrimeNG 17.13 we have been encountering unexpected behaviors with some components that now use the numberAttribute transform function for some inputs, probably because it is not defined a fallback value. The problem arise when the input is passed to the prime component, but with an undefined value (which is evaluated as NaN after being processed by the numberAttribute function)

Two examples:
In p-fileupload the input "filelimit" as undefined prevents the upload button from becoming active when a file is selected

In p-autocomplete the input "maxlength" as undefined renders the component unusable because the maxlength is ultimately evaluated as 0.
