[DataGrid] Avoid excessive calling of reinitialize method in JavaScript

[f4n0]

Pull Request

📖 Description

I've seen that the problem behind the strange resizing effect, is due to the JS method being initialized too many times.
I've not investigated a lot why but the method FinishCollectingColumns in FluentDataGrid.razor.cs is being executed each times a user click somewhere in the table. This will always re-execute the js method enableColumnResizing.

I've fixed the strange behavior by editing the js file in order to not re-initialize if the same grid was already initialized.
