Datatable multisort with optional metaKey, not default for multiple sort selection.

[rowanfuchs]

Allow multi-sorting in Datatable without requiring the meta key by default. Using a meta key as the default for multi-sorting is considered a UX anti-pattern, as it often necessitates extra explanations to inform users on how to sort by multiple fields.

A issue reported earlier is here:
primefaces/primevue#2716

The code in question would need an extra condition change with an additional property that toggles this functionality.
